SARAHKV asks: "My two year old neutered tom has been diagnosed with an autoimmune disease. He has been ill for 6 months, hair loss, open sores on his skin, high fever, coughing and general lethargy. We will hear from the vet tonight whether it is FIV or not, either way, can anyone tell me what his chances are? With each visit to the vet he has recovered for a couple of days before becoming ill again. Does anyone know if our other 3 cats could catch whatever it is he has?"
