There are five notorious feline diseases, or groups of diseases, that all cat parents should be familiar with.

Chronic kidney disease damages most of a cat’s kidney tissue so it doesn’t function normally. Common signs include drinking and urinating too much, weight loss and lethargy. Cats with diabetes have high levels of blood sugar, which cause similar signs. The same goes for cats with hyperthyroidism, but they might experience diarrhea and vomiting too.

Heart disease often causes rapid or labored breathing. In some cats, acute hindleg paralysis also occurs.

Finally, cats with cancer often eat less and lose weight. Other signs depend on which organs are involved.

Any of these diseases can develop slowly, but relentlessly. Knowing what to look for can help pet parents seek veterinary care as soon as possible.
