I volunteer at city shelter and am fostering a young male cat named Carson. The reason for the foster is he was not showing well in the adoption kennels at the shelter. He hisses and bats away those seeking to engage him when he is in the kennel. Shelter personnel thought some time away from that environment would help these issues. It hasn't. He's been to off site adoption events and back to the shelter but behavior hasn't improved. He is a totally different cat once at home - playful, loves to wrestle with my cats, snuggles on couch/bed, stalks - typical cat behavior. Problem is, his hissing and snapping behavior in kennel makes people avoid him - no matter how much you tell them he's wonderful once in a home environment. Time is running out, I think the shelter may decide to put him down. Any cat whisperers out there with suggestions on how get Carson to showcase better?
