Thread: Why would my MC Kitten suddenly pee & poop on my fluffy duvet? :(

I had a cat once that wee'd on my 'Then' boyfriends pillow. I was cross but also relieved it was his pillow not mine!! I personally think she was just marking her territory... Don't think she liked him much... Didnt take me that long to agree with her!
Maybe your cat is marking its territory stating to the other cats that you are his territory. It could feel threatened by living in such a large household of cats and feel the need to mark your space as his space.
