I'm surprised that hasn't happened yet with Pixel as she is always trying to get into cupboards!

Mum's cat, Milo, is another cupboard queen! She gave birth to a little of kittens on the very top shelf of the cupboard once

Another time, she got stuck in the laundry cupboard. Mum's laundry is basically a space hidden behind a concertina door. Above the washing machine is a set of shelves with a sliding door. Mum kept the towels in there, and one day Milo thought it would be a good idea to bed down in there. Well, she didn't turn up for dinner and we searched high and low for her. We found her sitting quite cosily on the towels. She was in there at least four hours!
