Cat will poop, but not pee in the toilet!
So I've been happily using litter kwitter for about a year now. My cat started using it as a kitten (about 5 months old) and was fully using the toilet for 3 months without any of the inserts, that is, up until two weeks ago. Now my cat will poop in the toilet, but refuses to pee in it. He is peeing on his cat beds (three of them), on the bottom of his kitty scratcher, on our couch, and on my sweatshirt. Nothing has changed, there are no other animals in the house, and he has his own bathroom all to himself (no one else uses it and I only clean it with ammonia-free cleaners). He only ever pees at night when we are asleep so I can't catch him in the act. Is there anyone else who is having this issue? Is there some way I can fix this behavior?
