9 Best Cat Foods for Congestive Heart Failure in 2020

You may not spend a lot of time thinking about your cat’s heart health, but maybe you should. Early signs of heart disease can be difficult to detect, but prompt diagnosis and treatment is your cat’s best chance for survival. Many forms of heart disease, once advanced, can lead to a serious and life-threatening condition called congestive heart failure.

Once your heart’s ability to properly pump blood becomes compromised, all of his other organs may start working overtime to make up for it. The longer this goes on, the more likely your cat is to develop secondary complications which can further weaken his body. Understanding the basics about heart disease in cats and knowing how to spot it will help you save your cat from having to endure this.

In this article, we’ll explore the different types of feline cardiomyopathy, including their underlying causes and common complications like congestive heart failure. We’ll also take a closer look at congestive heart failure in cats to determine the best medical treatment and to see how a change in diet could help. You’ll also see our top recommendations for the best cat congestive heart failure diet.

Heart problems in cats are typically divided into two categories: congenital and adult-onset. Congenital cardiovascular diseases are related to heart defects present when the cat is born and, though some cases show signs when the cat is young, many cases go undetected for years. Adult onset heart disease can occur following damage to the heart or could be linked to another hereditary condition the cat has. In many cases, the exact cause of adult onset cardiovascular disease in cats is unknown.

Though heart disease in cats can be severe, it is less common than it is in dogs. The most common form of heart disease in cats is adult onset hypertrophic cardiomyopathy, characterized by enlargement or thickening of the heart muscle.

Here are some of the most common heart problems seen in cats:

  • Hypertrophic cardiomyopathy (HCM)
  • Dilated cardiomyopathy (DCM)
  • Restrictive cardiomyopathy (RCM)
  • Intermediate cardiomyopathy (ICM)
  • Congestive heart failure (CHF)

In all types of feline cardiomyopathy, an underlying abnormality in the heart muscle leads to problems with proper heart function. The specific changes in function are related to the type of cardiomyopathy.

With HCM and RCM, the disease affects the heart’s ability to relax between contractions, preventing the heart from filling with blood effectively. This leads to a form of heart failure known as diastolic heart failure. With dilated cardiomyopathy in cats, the disease affects the heart’s ability to contract which also compromises its ability to pump blood. This leads to a form of heart failure known as systolic heart failure. Congestive heart failure develops when the heart loses the ability to effectively pump blood, causing fluid to eventually back up into the cat’s lungs.

In some cases, signs of heart disease develop slowly over the course of months or years. When heart disease is linked to physical trauma or an underlying condition, however, it may develop more quickly.

Here are some of the most common signs of heart disease in cats

  • Vomiting
  • Difficulty breathing
  • Thromboembolisms (blood clots)
  • Depression and isolation
  • Poor appetite
  • Unexpected weight changes
  • Swollen abdomen
  • Fainting or collapsing
  • Sudden hind leg paralysis
  • Weakness or fatigue
  • Restlessness

If you notice these symptoms in your cat, you may want to have your vet take a closer look for additional signs of cardiovascular problems. Your vet might check for a heart murmur, a gallop rhythm, abnormal heart rate, or cardiac rhythm disturbance, all of which could indicate cardiomyopathy in cats.

Now that you have a better understanding of common heart problems in cats, let’s take a closer look at congestive heart failure in particular. Read on to learn common cat congestive heart failure symptoms as well as treatment options and how changing your cat’s diet can help.

Treating Congestive Heart Failure in Cats

Congestive heart failure is seen most often in older cats, though it can develop in cats of any age. Because this is a serious disease, detecting the signs early can greatly increase your cat’s survival rate. Congestive heart failure develops when the heart can no longer effectively distribute blood throughout the body. In the early stages, the body adjusts to ensure that organs and tissues get the blood and oxygen they need. As the disease progresses, however, the body’s systems that are already working overtime start to struggle, causing fluid to backup in the body, especially in the lungs.

Here are some of the most common cat congestive heart failure symptoms: 

  • Lethargy
  • Weakness
  • Difficulty with exercise
  • Coughing
  • Labored breathing or panting
  • Loss of appetite
  • Grey or purple gums

When it comes to congestive heart failure, cat symptoms often appear gradually and can be easy to miss. As the fluid buildup continues, however, your cat’s ability to breathe properly can become compromised and may lead to additional complications.

Diagnosing congestive heart failure in cats usually involves determining whether the cat has an underlying condition contributing to the disease. Things like hypertrophic cardiomyopathy, high blood pressure, hyperthyroidism, heartworm, and anemia are often linked to CHF, as are heart defects and abnormalities in heart rhythm and function. Once your veterinarian determines the underlying condition, treatment can begin.

In severe cases, cats with CHF may require hospitalization until blood and oxygen levels return to normal. Fluid drainable and oxygen therapy may be required during hospitalization, or surgery in cases where a congenital defect is the problem. Changes to your cat’s diet may help with treatment, though your cat may still need certain medications like diuretics to remove excess fluid, vasodilators to improve circulation, or positive inotropes which increase heartbeat force. Many cats with congestive heart failure require medication for the rest of their lives.

What to Look for in a Good Cat Food for Congestive Heart Failure

According to some sources, cats with heart disease have no specific dietary requirements as long as they are able to maintain healthy body weight and obtain balanced nutrition. A balanced diet for cats should contain plenty of animal protein with adequate levels of taurine, an important amino acid. Low-sodium diets are unlikely to make much of a difference unless your cat’s heart problems are linked to high blood pressure. You may also want to consider giving your cat dietary supplements for vitamin E and other antioxidants as well as coenzyme Q10. Ask your veterinarian for specific recommendations.

Here are some other general things to look for in a good cat food for congestive heart failure: 

  • High-quality animal protein (ideally 35% to 40%). Cats are obligate carnivores, so they have a higher biological need for protein in their diets than dogs. Animal proteins are the most biologically valuable and they are complete proteins, meaning that they contain all of the essential amino acids your cat needs including heart-supporting taurine and carnitine.
  • Rich in omega-3 fatty acids from animal sources. Omega-3 fatty acids help reduce inflammation and may help protect against abnormal heart rhythm in cats with heart failure. Look for healthy animal-based sources like fatty fish (salmon or salmon oil) as well as plant sources like flaxseed and canola oil. Plant oils can also provide omega-6 fatty acids to balance out the omega-3s.
  • Low carbohydrate content with high digestibility. Cats have a limited ability to digest plant products and they have no specific requirements for carbohydrate in their diet. Digestible carbohydrates like whole grains and vegetables can, however, provide valuable nutrition as well as dietary fiber. Just make sure most of the main ingredients in the food are animal-based.
  • No artificial additives or by-products. Low-quality ingredients like fillers, by-products, and artificial additives have no nutritional benefit for your cat and should not be in his food. Look for a recipe that contains only natural, whole-food ingredients at the top of the list.
  • Beneficial supplements for heart health and balanced nutrition. Vitamin and mineral supplements are required in commercial foods to ensure nutritional balance. You can also look for heart-supporting supplements like taurine, omega-3 fatty acids, carnitine, B vitamins, antioxidants like vitamin E and magnesium. Probiotics (in the form of dried fermentation products) for digestion and improved nutrient absorption wouldn’t hurt either.

Again, only your veterinarian can say what’s best for your cat and his particular case of heart disease. When it comes to cat congestive heart failure, diet is an important factor in maintaining your cat’s ideal body weight and overall health. If you’re still not quite sure what to look for, read on to see our recommendations for the best cat food for congestive heart failure and to see how we made our picks.

How Do We Make Our Recommendations?

Because cats are obligate carnivores, they have a high biological requirement for meat in their diets. A real source of animal protein should be the first ingredient in your cat’s food and, ideally, the main source of fat. Carbohydrates provide limited nutritional value for cats, so any that are included in your cat’s food should be whole-food ingredients and highly digestible. These are some of the key things we look for before recommending a cat food. Complete and balanced nutrition is essential as well, so we also look for recipes fortified with essential vitamins and minerals.

Here are some of the requirements for a cat food to receive our recommendation: 

  • A source of high-quality animal protein as the first ingredient
  • At least 30% crude protein for kittens and at least 26% for adults
  • A minimum of 9% crude fat for kittens and adults
  • A balance of omega-3 and omega-6 fatty acids, primarily from animal sources
  • A rich blend of nutrients from natural sources and supplements, as needed
  • Limited carbohydrate content from digestible sources (like whole grains and veggies)
  • No low-quality fillers, by-products, or artificial additives (preservatives, dyes, or flavors)

All of our cat food recommendations are made based, first and foremost, on AAFCO food nutrient profiles. These profiles simply outline the minimum nutritional needs of cats in various life stages (kitten or adult). In order to determine whether a cat food meets these requirements, just look for an AAFCO statement of nutritional adequacy on the package. It should look something like this: [X Product] is formulated to meet the nutritional levels established by the AAFCO Cat Food Nutrient Profiles for all life stages. After you have successfully determined that the formula is complete and balanced, you can go on to evaluating its quality.

The 9 Best Cat Foods for Congestive Heart Failure

Follow your veterinarian’s advice if he recommends a prescription diet but don’t be afraid to ask questions. Many prescription diets are made with animal by-products and low-quality grains, so think twice before blindly following your vet’s recommendations. Ask whether a nutritionally balanced cat food made with whole food ingredients might provide the same benefit.

Frequently Asked Questions

  1. Are some cats more prone to heart disease? Any cat can develop heart disease if born with a heart abnormality. There are, however, certain breeds which are predisposed to certain types of heart disease. The Maine Coon is prone to hypertrophic cardiomyopathy and a recent study showed that 33% of cats of this breed had a genetic abnormality that was related to the disease. Persian cats also have a high incidence for the disease and both American and British shorthairs are prone to a less severe form of hypertrophic cardiomyopathy. Siamese cats are prone to patent ductus arteriosus (PDA) as well as dilated cardiomyopathy.
  2. Do grain-free diets cause heart disease in cats? Over the past year or two, there have been concerns about a potential link between grain-free commercial pet foods and an increased risk of heart disease in pets. Numerous accounts of dilated cardiomyopathy have been noted in dogs being fed grain-free diets, particularly in breeds and sizes that are not typically prone to the disease. The FDA is currently performing a more in-depth investigation to determine whether the link is clear. Though a few cats have been listed in the report, the problem seems to be more common in dogs. Cats require higher protein levels in their diets, ideally from animal sources. Commercial foods high in plant proteins are less biologically valuable, though it is unclear whether they can be linked to developing heart problems. Read the FDA’s report here.
  3. How long do cats live with cardiomyopathy? When it comes to feline cardiomyopathy, life expectancy varies among the different types. Cats with hypertrophic cardiomyopathy are prone to blood clots and if one develops, their situation could be dire. Even when the cat survives the first 24 hours, their prognosis is another 2 to 6 months. All forms of cardiomyopathy in cats are serious and could affect the cat’s lifespan. When it comes to cat congestive heart failure, life expectancy is only 6 to 18 months because severe damage to the heart has already been done and treatment may not be able to reverse it.
  4. Is heart disease painful for cats? There are a number of different types of heart disease that affect cats, each with a unique array of symptoms. For the most part, symptoms in the early stages are not painful and may not even be easy to spot. As the condition worsens, however, your cat’s heart function could become impaired and that may lead to more severe and potentially painful symptoms. With certain forms of heart disease, there is a risk for a painful and paralyzing condition called saddle thrombus in which a blood clot develops in the heart and moves out of the aorta to lodge in the saddle. This can lead to hind leg paralysis.
  5. What should you feed a cat with heart disease? There is no single “best” diet for cats with heart disease because medical and dietary recommendations vary depending on the type of heart disease your cat has. Generally speaking, you should look for a recipe that will help your cat maintain lean muscle mass and an ideal body weight to prevent putting extra strain on the heart. Some level of sodium restriction may be recommended depending on the stage of heart disease and nutritional supplements should be included to ensure that your cat gets balanced nutrition to avoid nutritional deficiencies. Certain supplements may also be beneficial for heart function like taurine, omega-3 fatty acids, antioxidants, and co-enzyme Q10.

Heart failure in cats is a serious concern, so take your cat to the vet at the very first sign of symptoms. With your vet’s help, you can diagnose your cat with a specific form of feline cardiomyopathy or another underlying heart problem and start treatment before it develops into congestive heart failure. If your cat has already developed CHF, you should follow your veterinarian’s advice to keep your cat healthy and comfortable for as long as possible.

When it comes to managing feline congestive heart failure, diet plays an important role in keeping your cat healthy and well. Your vet may recommend a prescription diet, depending how advanced the case is, or you might simply want to look for a heart-healthy diet that will help your cat obtain the balanced nutrition he needs while maintaining proper body weight and condition.
