My poor cat was in a fight last week, and has had to have the resulting leg abscess drained under sedation at the vets yesterday. The vet has advised to keep her in for a few days, which is not going down well with said cat, but we can manage that okay. She usually goes to the toilet outside, and we got rid of her litter tray a year or so ago. Obviously she uses litter trays when she goes to the cattery, so knows what they are. We have got a new litter tray for her to use, but she has now been home for 24 hours and has not used the tray at all, won't go anywhere near it. Should I be worried? I think it may be a ploy on her part to get me to let her out, kind of a battle of wills. Obviously I don't want her to get a UTI from not going to the toilet, but equally don't want her leg wound to get infected until it has healed over... Any advice appreciated!
