There were three in the bed

I bought this igloo-type cat bed, but instead of going inside, the cats prefer to lie on it. As soon as he comes in, one-eyed Beano (it's his eye you can see) commandeers it. But recently little black-and-white Mitzi has been insinuating herself into a corner of it beside him.

Her tortoiseshell daughter Twiglet (who is more than twice the size of her mother) has decided to join in the act. There are nine sleeping-places in total for seven cats, but they all seem to want the same one. Little cusses.
