If your fuzzy little feline is having trouble getting up the stairs or seems down and out, something more insidious may be causing his lethargy.
Cardiomyopthay (also known as heart disease) can affect animals, like your cat. It is the most common type of feline heart disease and causes fluid to build in the lungs and leads to heart failure. The disease is more common in breeds like the Himalayan, American short hair, ragdoll, Abyssinian and Burmese; though it can be found in other and mixed breeds.
