We used to keep our litter tray in our box room upstairs but now I'm 23 weeks pregnant, we will need that room as our nursery so we have got a new enclosed litter tray and popped it in the downstairs toilet, but our 1yr old cat doesn't seem to like it much. No accidents inside, I think he's going outside to go to the toilet, but he seems out of sorts, anybody got any tips for me? X
