Causes of Feline Myocardial Disease: Understanding the

Understanding the Known Causes of Feline Cardiomyopathy

1. Genetic Predisposition

Most cases of feline cardiomyopathy are attributed to genetic factors. It's important to note that any cat, regardless of age—be it a kitten or an elderly feline—can be susceptible to this condition. Cardiomyopathy can affect cats of all breeds, though certain breeds, such as Ragdolls and Maine Coons, may be more prone due to their genetic makeup. There is also a theory suggesting that male cats might have a higher risk of developing the disease than female cats. While the exact cause of most cardiomyopathy cases remains unclear, animal medicine experts have identified a complex relationship between the disease and deficiencies in taurine and hyperthyroidism.

2. Insufficient Taurine Intake

Cats that do not receive adequate taurine are more susceptible to cardiomyopathy. Taurine, a crucial amino acid, is vital for heart health, and a severe deficiency can lead to heart failure. In the 1980s, a significant number of cats were diagnosed with a related disease, which was later found to be primarily related to dilated cardiomyopathy, a condition linked to taurine deficiency. As a result, pet food manufacturers began fortifying their products with sufficient taurine, significantly reducing the incidence of taurine deficiencyrelated cardiomyopathy. While dilated cardiomyopathy is now less common, hypertrophic cardiomyopathy remains a concern.

3. Hyperthyroidism in Cats

It is wellknown that hypertension can be a symptom of feline cardiomyopathy. Hypertension might be caused by hyperthyroidism, which is another known factor contributing to the disease. Hyperthyroidism, often seen in older cats, may be associated with exposure to environmental flame retardants like PBDEs. These elements are primarily found in seafood rich in brominated flame retardants and iodine, such as certain types of tuna and mackerel. This serves as a cautionary reminder for pet owners to be mindful of their cats' seafood intake, particularly avoiding highiodine and brominated seafood, to minimize the risk of hyperthyroidism and, by extension, cardiomyopathy. Opt for shallowwater fish like sardines and mackerel instead.

So, what should pet owners look for when choosing seafood for their cats? It's best to opt for shallowwater fish like sardines and mackerel.

Dr. OxygenPet summarizes three known factors associated with feline cardiomyopathy. It's crucial for pet owners to be aware of these factors and take preventive measures. Ensuring that cats receive an adequate amount of taurine and staying informed about heart health are essential steps in reducing the risk of cardiomyopathy. By being proactive, pet owners can help avoid the headaches that come with this condition.
