I adopted two sister cats 4 years ago and we love them both very much. They have been spayed and declawed (dont judge.... they are strictly indoor cats) However for the past 6 mos or more one cat (Cuddles, a very loving socal cat) has stopped using the litter box so when I come home there is little cuddle gifts for me to clean up (thank god I have tile) We have gone the vet and there are no medical reasons. We seperated the litte boxes and food so that each cat has there own food/water dish and litter box noe of this has worked. We now have had to put her in a room of her own and when we try to let her out she resumes the pooping in the corner. While she is in her room she uses the litter box. But she is basicly in kitty jail with little interaction. I dont want to find another home for her but I am at this point so guilty for locking her up I dont know what else to do. Any help or suggestions would be greatly appreciated.
