I think the title might be a misnomer. It might not be that the pet has depression, but medication is a different approach to anxiety or behavior issues. There have been a few of those on Pet Talk but I don't know of any where the pet has been started on a medication specific for the behavior problem. I think it is worth mentioning because it might make an otherwise un-adoptable pet able to be adopted instead of pts. I wouldn't say there is a pat right or wrong answer though. I think it would depend on the pet, the person and the veterinarian. But if it can help maybe it is worth trying.
