My cat has recently started leaving 'presents' outside of the litter tray for some unknown reason. This year I moved out of my house to move back in with my mum who already has 2 female cats that are 9 years old. I have 2 male cats that are 3 (max) and 2 (lucas). Lucas has started leaving poos just outside of the litter tray even when the litter tray has been clean! I noticed that one of my mum's cats had done this a few times aswell. Does anybody have any idea why he is doing this? Is it under protest? I'm feeling quite bad that I have may given him some stress or something by moving my cats into a place where there are already 2 cats that they didn't grow up with!! Many Thanks Sian.
