We have glass back doors to our kitchen and a cat flap in a side door that is not see through. Our cat is sitting in the rain outside the glass doors looking at us mournfully and crying. Every now and then one of us will take pity on him and bang the cat flap to remind him he can actually move about one metre to the side and come in. This is not just today, it’s a regular occurrence and I don’t like opening the back door for him - it’s got three locks and also …. there’s a catflap! This is not new… he’s 4 and been using it for years. My question is … does he forget about it, not like using it in the rain… or something else? He comes and goes as he pleases so this really only happens when he can see us??
