This is a cat igloo, to keep my cat warm at night, it has become more of a hammock as the cat insists on sleeping on top of it! My cats all sleep in odd places, on the side of the bath, like a gymnast on the beam. Or halfway up the stairs. This is my biggest cats’ habit and since he almost fills a whole step it’s a good job he has some white fur so I can see him when I’m climbing up, or coming down stairs! He’s a real trip hazard!
