I have had this kitten for awhile. I got him a few days before I got my adult cat (Merlin). He was using the litter box just fine until he showed up. Now, Riku, goes everywhere but in the litter box. I don't want to give him away for a matter than can be solved. I am determined to get him to go into the litter box. I have a feeling they are fighting over it since they are both male. If anyone can help me out I'd appreciate it. I have shown him the litter box, moved it, placed tissue with his waste on it in the litter box and showed him it..nothing has worked.
