Bengal Odin

I need to find a new home for my baby bengal. He is playing too rough with his elderly 'sister' and she is having back problems that are getting worse. I live in a 750 sqft apartment, and have no space to separate them and cannot let them outside. Odin loves running on his 'one fast cat' wheel and rehoming fee will include many supplies including his wheel, self cleaning litter box, scratch posts & cat tree. He is purebred bengal, I can show you his papers upon request. He is very playful and affectionate, and LOVES water- jumps in the shower every time it turns on. He needs an owner who can give him lots of attention. He is not aggressive towards other animals, he's just young and playing to rough with the older cat. Asking for a rehoming fee of six hundred, which will include his supplies and help recoup some of my expenses. His parents are TICA registered and he is neutered.
