It does worry you to death.

We sleep with our bedroom window open so we have to close our door to stop them coming in through the night and try to escape, so far they haven't opened a door to let themselves in which I would have thought would be easier.

My two can open an internal door from inside a room - I haven't a clue how, it must be teamwork.

Hubby had put them in their room and closed the door, Duke wanted to go out to toilet at that point the phone rang. The kittens escaped their room and the first hubby knew was when he went to call Duke in, one kitten was in the kitchen and the other stood on the garden path, fortunately.

The play pen has arrived just in the nick of time as they are beginning to get curious about the outside world.
