Hi all, I have a tomcat 2.5 years old and neutered. I put in a cat flap in the front door (I live in a flat, nice and simple - on top of a ground floor one so door is on ground level). Before that for a short period of time he was coming in and out of the bedroom window where there is a sloping roof and he can jump onto a bin and down onto the ground. He is a fabulous cat and has been using the flap without any problem since it was put in. Two weeks ago he decided to go out the bedroom window again due to it being open for summer. He now will not use the flap at all. I don't want to encourage window use so have been calling him down from the front door. Sometimes he comes down, others not. I haven't seen him for 3 days now even though I have called him! I left a bowl of food out but it hasn't been eaten. Any advice? No changes in the home at all.
