We adopted an adult cat from an animal shelter (about 1 year old), he was very skinny and slept a lot, and soon we discovered he is FIV positive.

So far he underwent treatment, gained some weight, and is much more active. He doesn't play often, doesn't seek human company and prefers to keep to himself. Although he is okay with my wife's company when relaxed, he is easily spooked by me. He rarely seeks attention from any of us. Now he got to meow sadly through the house, and likes to hangout in the balcony. We think he is very solitary and misses cat company, and we want to get a female FIV positive to be his friend. He is neutered.

Do you agree with this assessment? Is a good idea to get another cat?
