I have 2 Savannah's that are three years old. One has perfect litter box habits and the other does not. My boy is an F3 and is very shy. I'm his favorite, my husband is second, no visitors see him. He has "his" room where his litter boxes and food are kept. He had a number of uti's but now that he eats wet food, he is fine. However, he pees on the mirrored closet doors, walls and closed doors. He has ruined one area on the wall. I keep the litter boxes clean and scooped. He also poops outside of his box. I've Tried cat attract, I encourage him and praise him. I've put him in a crate and he just pees threw the crate on the walls and carpet. I'm not sure what else to do. Any suggestions?
