It can be quite difficult to spot the signs of aids in cats in the initial stages. For one, felines are very capable of hiding illness from potential predators and owners alike. Also, cats infected with the virus may not show symptoms for several years after being infected. Lethargy and appetite loss are two of the most common signs of the initial stages of feline aids. Cats may also develop diarrhea or fevers. The lymph nodes may also start swelling up. Once feline HIV progresses though, symptoms will appear more serious. Cats start losing weight.
