Hello. We have a two year old cat who was litter trained since we adopted her from rescue. Since she was spayed and allowed out (about a year ago) she has always chosen to do her business in our garden. She doesn’t leave the garden. Even during the Beast from the East she chose to go outside. We still have litter tray for her for emergencies because we don’t let her out at night but it hasn’t been used for almost a year. She knows where it is. In the last week, she has chosen to scratch (like she would at litter) and poo on a silk Chinese rug every other night or so! I have been keeping the door to this room shut at night recently but last night DH forgot and she’s done it again. Why? And what shall I do? Btw, I’m booking her a vet appointment anyway because various family members have mentioned she looks “sad” or “down”. I’m worried she’s ill. Thanks.
