Hello so I have two kittens, a 12 week old male and a 13 week old female. We got the female first and she was with our 10 month old male cat who had been looking after her like a mama they used the same litter box together without any problems. When we got the male kitten a week later he used the same litter box without any problems for a week or so, however he’s lately been having random accidents and has peed in different parts of the house, both of the bathrooms and in my bed. He doesn’t seem to be having problems with getting into the litter box or anything and it is an adult size and pretty huge so I didn’t think sharing would be an issue for now. Although I would like for them to keep sharing the litter box ideally as we don’t really have another good place to permanently place another one. So I’m just wondering why he sometimes decides to not use the litter box and how we could prevent these accidents? Any help would be greatly appreciated
