Thanks everyone for your advice...
Tinky is definatelly the territorial one.. she battles throught the door while Jupiter sits safely in the hallway.. I don't know if she accidentally attacked him because of all of this but he definatelly knows NOT to get around Tinky. I was feeding the poor guy but I stopped because he wasn't coming around as often and the food was attracting too many ants. He is such a pretty cat I wish you guys could see him. I don't know if I want to do anything to scare him away because I want to trap him and get him to the vet. I like your idea of spreading the litter and wash water out in the yard though Debbie. I am going to sart doing that.
