We rescued our cat, Rockefeller, back in May this year. He is showing every sign of depression (we haven't taken him to a vet for this because we are trying to work through it on our own). He seems to comfort eat, he gets bored with things very easily (and he has no shortage of toys or things for stimulation). His life started out as a disney story; he was left on the side of the road in a carrier with his littermates. He was the last to be adopted, but the one before him had been with him up until just a couple of weeks beforehand. They mentioned at the shelter his demeanor had changed. He was also a very sick kitten as well. We have tried everything EXCEPT for any sort of medication/supplements. I'd like to stay away from any sort of pills. We are willing to get another animal, if possible, to help as that is really our last option that I feel completely comfortable with. We were looking into ferrets, or possibly a larger house rabbit. Rock is a pretty large cat, but he isn't aggressive. He's actually a bit ridiculously passive for such a young kitten, I think. He rarely sticks up for himself, but he is very playful, which is why I would prefer a ferret. Has anyone ever dealt with feline depression before? It is breaking my heart to think that he isn't completely happy here. After what he'd been through before, especially with his health, and his horrible separation anxiety (we're also working on this), I just hate thinking he is putting up with some sort of depression as well. Is this something we really should see a vet about?
