I have two spayed female buns in the same room and they take turns having free roam time due to them not being bonded. One of them are super territorial of her cage, and pees outside of the other buns cage any chance she gets and it's getting really annoying and ruining the carpet!! She always had perfect litter habits I've had both buns for 2-3 years, so this just recently started and I know its territorial peeing because she'll only pee outside other buns cage. How do I get her to stop this!!??? Please and thank you for advice
