@jacklaridian I got him neutered, vaccinated, checked out by a vet, and tested for feline leukemia and HIV (negative for both.) He doesn't have fleas or parasites. She says he's totally healthy- he had an ear infection so she gave him a shot & some drops I can give him.
Ok, thanks for the info- that's helpful. I've never had a male cat and my cat's never been around another; I've been googling but it's giving me conflicting info.
