Yes, my Bobby is also FIV+. Cats do NOT get sick and / or die from FIV. It weakens the immune system, so they need more help fighting off illness and disease. There is an underlying problem which it sounds like has not yet been diagnosed.

Something as simple as a URI, aka "kitty cold," can be tough for an FIV+ kitty to fight off. My vet will start antibiotics sooner w/Bobby than with another cat.

Also, an FIV+ cat should not have a regular rabies shot, which includes live rabies virus. They get the rabies shot with the killed virus.

Finally, FIV is NOT diagnosed from a stool sample! It is diagnosed from a blood test.

Please take Gabby to another vet.
