It's one of those 4 way ones with the red and the green sliding catch. We usually set it to either in & out or just in. We've been locking it on in in the evening but one of our cats has worked out how to slide the catch over and let himself out. The trouble with this is that he then leavs it free for my other cat to escape.
If I block it off in the evenings and one of my cats is already out then they won't be able to get back in. Any ideas?

Are you suggesting the OP should take a screwdriver to his cats?!
