Oriental kittens & cats in Anderson, South Carolina

We rescued Delilah as a three week old abandoned kitten. She is now 5 and a half years old. She has been solely an indoor cat her whole life and needs to remain indoors. She is completely declawed (all 4 paws) so she is defenseless outdoors. She loves to cuddle and can be playful at times. It takes her a minute to warm up to strangers but she adores children. We have to rehome her because she started marking in the house after we moved. She refuses to share the cat box with our other cat. We separated them for a while and she was fine using the box without another cat around. It is not feasible for us to keep her at my business long-term and I'm afraid somebody will accidentally let her out. She has a great personality and we would just deal with this behavior if it wasn't causing health issues for our granddaughter. We were advised by the pediatrician to rehome her.
