We have a four way cat flap that can be locked in the following options.

: Locked in both directions (Cat can't go anywhere)
: Locked Out Only (Cat goes out but not in)
: Locked In Only (Cat goes in but not out)
: Open both ways (Cats go where they like)

Now Milo has often been found on the wrong side of the door.

There has been arguments about who let him out, or you must have left a window open ?!?

In fact today, I have been looking to see if he could have got though an air vent.

This evening the cat flap was in in only and we catch Milo pulling the cat flap door towards him, using his claws on the seal, so he could leave.

We were speechless, what a clever kitty. But how do we keep him in now ???
