My beautiful/daft cat won't use the cat flap. He'll go through it if it's propped open but it's cold now and we can't do that. We've tried treats, holding it open for a short time, encouragement, wiping him with a clean cloth to get his scent and then running that around the cat flap.. It's now a problem because he caught him weeing in a large indoor plant pot this morning!
Any other ideas please!!
