Unleash Their Inner Lion: Exercising Your Kitten

Although your new kitten may spend much of their day catnapping, they will likely be up for a few play sessions a day, too. Through regular play cats receive much of the exercise they need, which is not only great for your new kitten’s physical well being but for their mental health, as well.

Cats are natural hunters and their play style mimics these traits by stalking, chasing and catching objects. Although play sessions may only last 10 to 15 minutes at a time, they can happen a few times a day. It is a great idea to encourage these sessions early in the day and again before bed to get your cat into a routine of being active when you are also awake

In the beginning, you may need to encourage play with your new kitten, but as time goes on your kitten will catch on and often be the one to initiate play sessions with you or your family.

with you or your family. Need some ideas on how to keep your cat playful and exercised?

THINK VERTICAL

Cats love to climb. Providing your cat multiple levels to investigate will not only allow them the opportunity to get some exercise but also to see their surroundings from a different angle. To do this you may want to consider purchasing a cat tree, which consists of multi-level platforms for your cat to climb and explore. These are often covered in carpet-type materials which also encourage your cat’s natural need to stretch and scratch their claws.

 

SWITCH UP THEIR TOY SELECTION

Sometimes boredom can set in when it comes to play if the same toys are always available. Make play sessions more interesting by rotating available toys. This is will keep things fresh and exciting.

 

TOYS THAT BRING OUT THEIR NATURAL INSTINCTS

It’s no surprise that cat toys are often fashioned to represent small creatures like mice and birds, which also happen to be the main animals cats hunt. These will be some of your cat’s favourite toys. Small toy mice and feathered toys that your cat can bat around and chase will provide endless opportunity for play.

If you want to interact with your kitten during play, consider feather teaser toys that dangle feathers from a long string on a handle that you can flick, move and drag around the house mimicking a bird.

Laser light toys are also great to use, as long as you keep them out of your kittens eyes and at ground level, to stimulate their hunt and catch instincts. It is amazing that a small light that you control around the room can catch their inquisitive nature by imitating the movements of a bug.

 

TAKE ADVANTAGE OF YOUR NATURAL SURROUNDINGS

Cats love to watch birds and are inquisitive about the outdoors in general. It is not uncommon to find them sitting at the window or looking out the screen of a door. This mental stimulation is beneficial for them. You may want to consider installing a cat window perch so they can have abundant nature views.

If you have the space, many cat owners are now installing “cattios” to allow a safe, enclosed space outdoors for their cats to investigate their natural surroundings while being protected from any risks. Cattios consist of an enclosure with multiple levels to explore that is placed outside, beside your home, near a window or door that your cat can access from the inside of your house. Preassembled cattios can be purchased for installation, or they can be easy to create on your own.

 

CAT TREAT DISPENSERS

Treat- or food-dispensing toys are great for keeping your pet’s mind active. These puzzle-type toys provide mental stimulation as your cat tries to figure out how to get a reward out of them.

interactive with your kitten, and it also fosters the bond between you while reinforcing their physical and mental health. A cat with a well-exercised mind and body has the best chance at preventing obesity and negative behaviours, such as house soiling. To learn more about how you can include exercise and play in your kitten’s daily routine, ask your veterinary healthcare team.

Thinking Inside The Box

Cats tend to have a strong instinctual drive to bury their feces, and find litter boxes an attractive place in which to do this. Most cats are trained at three to four weeks of age by their mothers to properly eliminate in a litter box. Soon, they follow her lead and begin to eliminate in the litter box on their own.

Some pet owners find litter with additives that attract the cat helpful in piquing their interest in using the box

This is useful for new kittens and cats that have mainly been used to eliminating outdoors. Outdoor cats can also be gradually trained to use a box in the house; start off using potting soil or sand in the box, and then slowly introduce a commercial litter product.

 

PICKING THE RIGHT BOX

There are many available options for litter boxes, including the traditional rectangular THINKING INSIDE THE BOX PHOTO: DEPOSITPHOTOS.COM SIFTING THROUGH THE FACTS ON KITTY LITTER By Kristina Cooper, RVT >> CAT CARE GUIDE 2018 PETS 19 GUIDE TO CAT CARE box, the covered box and self-cleaning variations. Most boxes are constructed of plastics that can be easily cleaned with soap and warm water, but may over time absorb odours and need to be replaced.

The least expensive and most accepted style tends to be the traditional plastic, rectangular box. Select one with enough room for your cat to move around without touching the sides too easily. Because these boxes are not covered, they are less confining and provide more air circulation. Their downside is that litter may be pushed out of the box if your cat is an aggressive digger. If the box isn’t large enough for your cat, or your cat has bad aim, they may also inadvertently eliminate outside the side of the box.

The covered boxes are moderately priced, and are especially fancied by those who have inquisitive dogs or whose cats may have bad aim. These boxes greatly reduce the amount of litter that is spilled outside of the box during digging. One downfall of this design is less air circulation, potentially resulting in odour buildup. They can also be too confining for larger cats.

The automatic self-cleaning boxes are the priciest option. These products automatically rake or sift the litter and remove clumps of urine and feces, depositing them into a reservoir that the owner can later empty. Although these boxes can cut down on cleaning time for busy cat guardians, the rakes can sometimes become stuck. Some versions tend to be a little noisy, as well.

 

LITTER BOX LOCATION

Cats are very selective creatures when it comes to eliminating, and do not enjoy an audience. The location of your litter box should be inviting, where there is both privacy and a low traffic flow. Keep in mind the location should be easily accessible to your cat, and the area should generally be quiet. Inadvertent noises (such as a furnace motor or clothes dryer buzzer) may startle your cat while in its box, which can result in an aversion to its use.

 

MOST CATS ARE VERY PARTICULAR ABOUT THE CLEANLINESS OF THEIR LITTER BOXES. SOME CATS EVEN PREFER TO URINATE IN ONE BOX AND DEFECATE IN ANOTHER, AND SO YOU MAY BE WELL OFF TO PROVIDE TWO BOXES.

 

LITTER TYPES

Clumping litter products are most commonly used. These litters clump around feces and urine, sealing it off from the fresh litter and allowing for easy scooping and removal. Although clay clumping litter appears to provide the strongest clumping action and is most widely used, some people prefer to use the newer pine-, corn- or wheat-based products. These litters tend to be lighter, and because they can be flushed or composted are more environmentally friendly. The downside of corn and wheat litters is that they may strike your cat’s fancy as a food source. And, although humans tend to associate the smell of pine with cleanliness, pine litters may be too strongly scented for cats and can lead to litter box aversion. There is a certain amount of dust to be expected with any clumping product, but some brands are less dusty than others.

Also available in pets stores are crystalline products containing indicators that alert you when its time to change the litter. These crystals, often made of silica, absorb urine and eliminate odours. They also have low dust levels. Feces must be scooped daily when using these products, and the crystals must be mixed to prevent any pooling of urine at the bottom of the box. Note that these litters can often be expensive, and that some cats find the sensation of standing in them unpleasant.

There are also litters that are made of recycled newspaper formed into pellets. These products are often used after surgery and declawing procedures to avoid contamination and infection. These litters do not clump, nor do they provide much odour control — meaning the litter box must be cleaned more frequently.

CLEANING THE BOX

Most cats are very particular about the cleanliness of their litter boxes. Some cats even prefer to urinate in one box and defecate in another, and so you may be well off to provide two boxes. In multi-cat households, some cats will not eliminate in a box used by another cat. Multi-cat households should have at least one box per cat, plus one extra, to meet their needs. It is paramount that your cat’s box be kept as clean as possible — remember that cats have a much stronger sense of smell than we do!

When using clumping litter, the box should be scooped daily and new litter added to top it up. Depending on the use of the box, it should be completely emptied, washed and refilled with fresh litter every few weeks. In the case of traditional claytype litters that don’t clump, it is best to completely empty, wash and refill with fresh litter on a daily basis. Silica crystal litters that don’t have a change indicator should be disposed of after one month. The box should then be thoroughly cleaned and refilled with fresh litter.

Although scented litters and deodorizers are appealing to people, use them with caution. They can be extremely strong and offensive to a cat, causing them to eliminate elsewhere. Unscented litters will retain their freshness as long as they are frequently cleaned.

Fractured Teeth Always Merit A Trip To The Veterinarian

Teeth are amazingly strong! Nevertheless, when you consider that teeth are essential tools for your cat or dog, used not only for eating but for playing and picking things up, it’s not surprising that veterinarians routinely see broken teeth in their patients.

“All types of dogs and cats can fracture teeth. Cats are more likely to have injured teeth as a result of trauma, while dogs often cause damage chewing during play,” explains Dr. Katherine Kling, a veterinarian at the University of Illinois Veterinary Teaching Hospital in Urbana who is pursuing board certification in dentistry. (When teeth are damaged due to trauma, such as bite wounds or being hit by a car, the teeth are generally treated after more serious problems, like jaw fractures, have been addressed.)

 

COMPLICATED OR UNCOMPLICATED FRACTURES

According to Dr. Kling, commonly fractured teeth include the fang-like canine teeth in dogs and cats (yes, cats have canine teeth!) and the carnassial teeth in dogs. The carnassial teeth are the largest teeth in your pet’s mouth, paired top and bottom toward the back of the mouth; these teeth evolved in many carnivore species to shear the flesh off prey.

Dr. Kling categorizes broken teeth as complicated and uncomplicated fractures. Either way, the problem should be promptly evaluated by a veterinarian to save the tooth, in some cases, and to ensure that the pet is not in pain, in all cases.

“A complicated fracture occurs when the crown of the tooth is fractured and the pulp is exposed,” she says. “If there is not intervention, the tooth will die.”

Uncomplicated fractures do not involve the pulp (the part of the tooth that supplies nutrients to the tooth) and may heal. However, it is important to understand that fractured teeth can be quite painful and always merit a prompt visit to the veterinarian.

 

VITAL PULP THERAPY

Dr. Kling explains “If you notice a complicated fracture right away, there is a chance that the tooth can be saved through vital pulp therapy.”

 

A PAINFUL TOOTH IS PROVIDING NO BENEFIT TO A PET AND IT IS LIKELY TO CAUSE PROBLEMS. MOST ANIMALS EAT MUCH MORE COMFORTABLY ONCE THE PAINFUL TOOTH IS REMOVED.

Vital pulp therapy is generally performed by a veterinary dentist, like Dr. Kling. The procedure involves removing about four millimetres of the exposed pulp — the live tissue inside the tooth — and medicating the remaining pulp to help support new dentin as it forms. Dentin is a bonelike substance that lies below the tooth enamel; dentin is produced throughout the life of the tooth. To successfully restore viability of a tooth, vital pulp therapy must be performed immediately following the damage.

 

ROOT CANAL OR EXTRACTION

If time has elapsed since the tooth was damaged, two options remain for a tooth with a complicated fracture: a root canal or extraction of the tooth. Your veterinarian can help you decide between these two therapies.

During a root canal, all of the pulp is removed from the tooth and replaced with a substance that allows the tooth to function comfortably without the risk of infection or pain. If surgical extraction of the tooth is chosen, animals typically live happily with fewer teeth.

“A painful tooth is providing no benefit to a pet and it is likely to cause problems,” says Dr. Kling. “Most animals eat much more comfortably once the painful tooth is removed.”

Uncomplicated fractures usually do not need an aggressive intervention, but should still be seen by a veterinarian. While there is a lower risk of the tooth dying, the tooth may be sensitive. Additionally, the tooth may need some restoration or smoothing of jagged edges to ensure that it does not cause problems for the pet.

 

EVEN BABY TEETH NEED ATTENTION

Even if your pet is young enough that the fractured tooth will eventually fall out and be replaced by the adult tooth, a veterinarian needs to evaluate the problem

“Since permanent teeth are very close to their deciduous counterparts, pulp exposure on a baby tooth can result in damage to the bud of the permanent tooth below,” warns Dr. Kling.

While tooth fractures cannot always be avoided, choosing appropriate toys can help prevent fractured teeth in dogs that like to chew. Soft rubber or stuffed toys are much safer than hard plastic toys, antlers or bones.

“Dental issues are sometimes overlooked because they are not life limiting, but they are most definitely quality-of-life limiting, so it is important to include dentistry in your pet’s care,” says Dr. Kling. “We are fortunate to have the knowledge and resources to help provide our pets with comfortable and healthy mouths.”

Cats Are Carnivores, So They Should Eat Like One

Diet can have a big impact on health. Just like humans, cats have special dietary needs to help them stay healthy.

However, feline diets are a lot different than human diets. Cats are obligate carnivores, meaning they require meat in their diet and need little carbohydrates.

In the wild, cats usually prey on small animals, such as mice and birds. But as a pet, a cat might only be preying on a can of cat food. Because pet cats often don’t get the opportunity to hunt for their own food, it’s important for cat owners to mimic the high-protein, low-carbohydrate diet their cat would naturally eat in the wild.

Dr. Deb Zoran, a professor at the Texas A&M College of Veterinary Medicine & Biomedical Sciences, said the best way to mimic a cat’s natural diet is to feed them canned food that has a protein content of 40% or higher and a carbohydrate content of 10% or lower.

Eating canned food will also help your kitty meet their daily water needs.

“Cats are used to getting a large percentage of their daily water needs from their diet,” Zoran said, adding that if a cat is primarily eating dry food, it may have a harder time staying hydrated. “All dry foods are low moisture, so cats that eat only dry foods consume less water and are more prone to dehydration.”

Dry food diets can also present other health challenges because they are typically high in fat, carbohydrates and calories. In fact, a high-carb diet can lead to obesity and diabetes, Zoran said.

In addition, a dry food diet may also upset your cat’s stomach, since cats are not “built” for carbohydrate digestion and absorption.

So what should you feed your cat? Zoran said it is best to choose a canned-food diet that says on the label “complete and balanced.” If you want to feed a homemade diet or other type of whole-food diet, Zoran said that’s OK, too. Just make sure to consult a nutritional expert to ensure the diet meets all of your cat’s needs.

Additionally, it’s OK if you want to give your cat a treat every now and then. Zoran recommended plain, cooked meats that are not seasoned and do not contain onions and garlic, which can be toxic

Other foods that can be poisonous for pets include fruits such as grapes and raisins. In fact, Zoran said to avoid giving your cat fruits and vegetables unless your vet has given you permission.

There are also many plants that are toxic to cats, such as Easter lilies.

“They are extremely deadly to cats,” Zoran said. “Chewing on a single leaf can cause kidney failure.  It is best to know what plants you have before you put them in the house.”

As a cat owner, it is your responsibility to keep your pet safe from potentially harmful foods and to take your cat’s dietary needs seriously. As the old saying goes, you are what you eat!

Heart Disease In Cats

Heart disease is a common cause of illness in domestic cats. It is frequently called a “silent killer.” This is especially true in feline medicine due to the lack of early signs of disease and the tendency for cats to hide illness. While other species may exhibit early signs, such as coughing or exercise intolerance, cats are often subclinical (without signs) until the disease has become advanced.

Heart disease refers to any dysfunction of the heart and is different from heart failure. Many types of heart disease exist in cats, but the most common are called “cardiomyopathies” (diseases of the heart muscle). Other types of heart disease may include valve disease (such as mitral insuf- ficiency), birth defects (such as holes or strictures) or other conditions.

The most common heart disease in cats is hypertrophic cardiomyopathy (HCM). This disease is characterized by a gradual thickening and weakening of the heart muscle. As the muscle thickens, there is less room for blood to fill the heart and the muscle is less able to pump blood effectively as it weakens. There are two primary forms of HCM — a genetically linked form that is often early onset and occurs in some breeds (Maine Coons, Ragdolls, Rexes, Sphynxes and others) and a sporadic form that may occur in any cat at any age.

Dilated cardiomyopathy (DCM) used to be a common disease in cats and is characterized by a thin and “flabby” heart muscle. DCM was almost exclusively caused by a deficiency of a nutrient called taurine in the diet. In recent decades all commercial foods have been supplemented with taurine, rendering the disease less common. DCM may still occur for other reasons, or in cats fed homemade or poorly formulated diets defi- cient in taurine. It is important to note that taurine supplementation is likely not helpful in cats with other forms of heart disease.

Other cardiomyopathies exist, such as restrictive or unclassified cardiomyopathy; however, they are less common.

 

SIGNS

Early signs of heart disease in cats are easy to miss as they are either non-existent, or so subtle and non-specific that they are rarely noticed by owners. To further complicate matters, cats seem to know their own capabilities and limitations and tend to restrict their level of activity, which can further mask clinical signs.

Heart murmurs may be present in cats with heart disease. A murmur is an extra “whooshing” noise between normal heart sounds due to turbulent or abnormal blood flow. Some kittens may have a transient “physiologic” murmur that is of no signifi- cance that disappears as they mature. Approximately half of adult cats with heart murmurs will develop heart disease, while the other half will be healthy. The murmur’s loudness is not always associated with disease severity. While cats with heart murmurs should be monitored due to higher risk of disease, they will not all experience heart failure. Only about half of cats with heart failure will have a murmur.

Cats may also have an arrhythmia (irregular heart rhythm that may be fast or slow) or a gallop (an extra heart sound). Unlike a murmur, these are almost always signifi- cant in cats and should be investigated.

Other signs of heart disease are less specific and may include weight loss, loss of appetite, lethargy or collapse. Swollen abdomen and coughing are very uncommon in cats, unlike humans and dogs.

Cats with heart failure may develop slow and progressive signs, or may present acutely ill. Two main acute syndromes occur in cats — congestive heart failure (CHF) or feline aortic thromboembolism (FATE).

Cats with CHF develop an increased respiratory rate (generally more than 60 breaths per minute). They often breathe with an open mouth, may struggle for breath and have blue-tinged gums. Fluid may be present within the lungs (pulmonary edema) or around them (pleural effusion). Fluid may also build up in the abdomen or within the heart sac, though these signs are seen less commonly.

Cats with FATE generally lose the function of one or more limbs. Initially, the embolism is very painful, with loss of pain sensation occurring over the next few hours. The affected limbs are cold to the touch and without pulses in the arteries to the affected leg(s), and the limbs are weak or paralyzed. This is a very serious condition and is an immediate medical emergency for which prompt therapy is essential. While FATE classically affects the limbs, cats may also have clots to their brain (stroke), lungs (pulmonary thromboembolism), heart (myocardial infarction), gut (mesenteric clot) or in other locations.

 

RISK

All cats are at risk of developing heart disease; however, some breeds are at higher risk. These include the Ragdoll (and related breeds), Maine Coon, Sphynx and Rex breeds. Cats eating poor-quality, taurine12 PETS CAT CARE GUIDE 2018 WWW.PETSMAGAZINE.CA HEART DISEASE IN CATS BY KATHLEEN CAVANAGH, DVM >> GUIDE TO CAT CARE PHOTO: DEPOSITPHOTOS.COM deficient diets are also at higher risk for DCM. Congenital heart issues are uncommon in cats, but may include valve stenosis or insufficiency, patent ductus arteriosus (PDA), tetralogy of Fallot and others.

For most cats, not much can be done to decrease the risk of heart disease, though careful monitoring is recommended to allow prompt intervention.

While obesity is associated with many illnesses in cats, there is no evidence it predisposes to heart disease (cats do not get coronary artery disease like humans). Some infections (such as dental infections) may slightly increase the risk of endocarditis (infection of the heart), though this is not common.

 

DIAGNOSIS

Careful history taking and physical exams form the basis of diagnosis of heart disease. The examination will include listening carefully to the heart and lungs and checking for normal pulses.

The veterinarian will endeavour to rule out other diseases that may resemble heart failure, including pneumonia, asthma, cancer, trauma or other concerns. Cats having signs of blood clots may be confused with cats having other conditions, such as brain disease, muscle or skeletal disease or other conditions based on the location of the clot.

Chest X-rays are frequently recommended as a first diagnostic step if the cat is stable. The X-rays may show heart disease definitively, but more often are used as one part of a multi-step diagnostic process. Blood tests may be needed to rule out other conditions. Some specific tests (such as ntpro-BNP) may be useful in determining if heart disease is present. Electrocardiography (ECG) measures electrical signals through the heart and is useful for further evaluating arrhythmias.

The best way to determine the type and extent of heart disease is with echocardiography (ultrasound of the heart). This test is minimally invasive and usually does not require sedation. It allows images and videos of the heart to be collected and analyzed. This may be done by a cardiologist, veterinarian or skilled ultrasound technician and may be analyzed in house or sent away. While it may be more expensive than other tests it usually gives the most information.

 

MANAGEMENT AND TREATMENT

Heart disease in cats is rarely curable, with very few exceptions. Few surgical management options exist and the focus is medical therapy. There is little proof that therapy before the onset of CHF is effective at slowing the progression of disease in most conditions, though some potential therapies exist. Blood thinners may be used to prevent clots in cats with known heart disease, antiarrhythmic may be used if an arrhythmia is present, but other drugs are likely of limited effectiveness.

As discussed, taurine supplementation may be used in cats with taurine-deficient DCM, but this is very uncommon in Canada. It is not effective for other forms of heart disease.

In an emergency situation, cats with CHF may require oxygen therapy, diuretics (medications that increase the amount of water and electrolytes expelled in urine), chest taps (removal of fluid from around the lungs) and more aggressive care in some cases. Cats with blood clots will require pain control medication, anticoagulants and aggressive hospital care.

After initial stabilization, cats with CHF will almost always be treated with furosemide (a diuretic) to keep fluid off the lungs. They may also be treated with beta blockers (such as atenolol) to slow the heart rate and reduce certain symptoms, ACEinhibitors to help decrease fluid buildup, blood thinners to prevent clots or one of several other medications based on veterinary recommendations.

The prognosis for most cats with CHF is very guarded. Most cats can be stabilized through an initial crisis, but some do not survive initial hospitalization. After leaving hospital, most cats survive for three to six months with therapy. Some rare cases have been known to go into remission, usually young cats that experience CHF after a stressful event, but this is not common.

The prognosis for FATE is much more guarded, especially if severe signs are present. Many cats with saddle thrombosis (clot stuck at the junction of hind limb arteries) do not survive hospitalization, though some may recover fully. Treatment with a blood thinner, such as clopidogrel (Plavix®), is generally lifelong.

Consult your veterinarian immediately if you suspect your cat has heart disease. Prompt workup and therapy may improve prognosis.

Talk to your veterinary healthcare team for more information about heart problems in cats, especially if you own a breed known to be prone to cardiomyopathy.

Praising The Annual Checkup

As a veterinarian, one of the most common things I hear people say is that they do not need to bring their cat to the vet because their cat does not go outside. The American Veterinary Medical Association published a report listing some shocking, related statistics — among cat owners, nearly 45% say they do not take their cat or cats to a veterinarian annually.

It’s a sad statistic, because annual examinations provide an extremely valuable opportunity to perform a full physical examination, which can be crucial in detecting disease processes before a patient shows signs of illness, especially in cats. These are the most common silent or hidden illnesses in cats that can often be detected early with the help of a trusted veterinarian.

 

HYPERTHYROIDISM

Hyperthyroidism, the most common hormone imbalance in cats, is a disease of the thyroid gland in which a benign growth in the gland produces too much thyroid hormone. The thyroid hormone is responsible for setting the body’s metabolic rate. When there is too much of this hormone, the body’s metabolism significantly increases, which can result in a variety of symptoms, including weight loss (despite a normal to excellent appetite), muscle deterioration, heart disease and high blood pressure. Untreated, hyperthyroidism can lead to heart failure, sudden blindness or sudden death. Fortunately, hyperthyroidism can be diagnosed with a simple blood test. Most cats respond very well to treatment and can continue to live with a very good quality of life. Treatment options include oral medication, prescription diets, radiotherapy and surgery.

 

CHRONIC KIDNEY DISEASE

Chronic kidney disease (CKD) is a progressive, irreversible loss of kidney function. CKD is the most common kidney disease of cats and affects almost 3% of the general feline population. Though CKD can affect cats of any age, it is most common in older animals. Studies have reported that 30% of cats over the age of 15 years have CKD. Cats suffering from it will often display signs of increased thirst and/or urination, weight loss, high blood pressure and muscle deterioration. Kidney function can be easily evaluated with a blood test and a urinalysis. CKD cannot be cured; however, there are many treatment options that can be utilized by your veterinarian to slow down the disease process, including prescription diets and medications. Many cats can be treated successfully and can look forward to months or often years of quality of life.

 

DIABETES MELLITUS

Diabetes is a metabolic disease that results in high blood sugar levels over a prolonged period of time. Most cats suffer from type 2 diabetes, also known as non-insulin dependent diabetes. Symptoms may include weight loss, increased thirst, frequent urination and increased hunger. Left untreated, diabetes can result in death. Diabetes is commonly detected by testing for high glucose (sugar) levels in the blood and/or urine. Insulin injections are needed to treat most diabetic cats, but there is the potential for the diabetes to actually resolve or go into remission. Once a cat enters remission, the disease can often be controlled with a proper therapeutic diet — and the cat can enjoy a great quality of life.

 

HYPERTROPHIC CARDIOMYOPATHY

Hypertrophic cardiomyopathy (HCM) is the most common acquired heart disease in cats. One study found that the prevalence of the disease in cats could be as high as 30%. HCM is a disease of the heart muscle in which the muscular walls of the heart become too thick (or hypertrophied). This thickening results in the heart having to work too hard to pump blood out of the heart to the rest of the body. Veterinarians often detect signs of HCM early by listening to a cat’s chest during a physical examination. An increased heart rate, heart murmur or extra heart sounds may be noted as the diseases advances. HCM is usually definitively diagnosed by an ultrasound of the heart (echocardiogram). There is currently no cure for HCM, but once diagnosed, most cats can be properly monitored at home and by a veterinarian for signs of heart failure — at which point medication can be initiated to help support the heart and the patient.

Cats are natural predators and have evolved to hide pain and illness. Even the most experienced owner may miss signs that indicate that their cat is sick. By working with a trusted and skilled veterinarian, many diseases can be detected early on physical examination, which can result in a longer and happier life for your feline friend.
