Right, so my boss got a 10 year old rescue cat a couple of months ago. She specifically asked for an outdoor cat and they said she was. However, said cat seems scared of the outdoors, doesn’t like the cat flap etc. Boss can’t stand the litter tray. I suggested putting a bit of litter outside where she wants cat to go to the toilet and showing her it. That worked for 3 days but then the cat has now started refusing to go outside and is weeing and pooing inside even though litter tray has been removed. Boss wants to send cat back to rescue. Is there anything else she can try? I’d take the cat but our existing cat hates other cats.
