You should try & contact Jackson Galaxy. Maybe he can help you for free, for his show?? (or out of the compassion he has for helping people & their cats)Hey guys...thank you all for your advice. Unfortunately, I don't have the "outdoor enclosure" option. I live in an apartment. I would love to get in touch with an animal behaviorist, but I probably wouldn't be able to afford it. I need to do some more research into it. I have been looking around for no-kill shelters or someone who could possibly give him an outdoor environment to live in. I definitely don't want to have him put down...but it's like something inside of him snapped. My friends have even talked about how he looks different now..in his eyes. He just looks like he's ready to attack at any moment. When I walk around the house he follows me and scratches me whenever he gets the chance. He gets the fuzzy tail and hisses as well. I don't know what has gotten into him. The vet says he can't find anything wrong.
You never know, anything is worth a try. It never hurts to ask.
