I don't know , they're never in it . They don't sleep with us at night and it's to high for Chloe to get on during the day , even Sydney can't jump up there too easily so she just doesn't bother . Besides I don't really want them hanging out on my bed.
On weekend mornings when Chloe does sometimes get on my bed , she runs around in circles and buries herself in my pillows
so I guess she likes it.
