We have two adult cats (4 & 5 years old) and recently adopted a kitten from a shelter. He developed an URI within a day of coming home, and our vet believes, because of the way his eyes are affected, that he has FHV. We've been treating him with oral antibiotics, antibiotic eye ointment, and Enisyl-F for about 3 weeks, but his eyes are still pink-rimmed and runny (though they do show improvement often, it never lasts more than a day or so before looking bad again). My husband is ready to give up on him (especially after he learned the Enisyl-F would be a life-long thing). He's mostly concerned about our other cats contracting the virus. We've kept the kitten separated from the other cats, but he's going stir-crazy being in a small bedroom all the time. Does anyone have any experience with this type of thing? How worried should we be about how this would impact our other cats? (I've read that most cats have already been exposed to it, and that it generally doesn't affect older cats as badly as kittens). Sorry this is so long. Any feedback would be GREATLY appreciated!! Thanks.
