Queen size here. It is just fine for me and the three cats, even though my cats don't like to snuggle close to each other. Usually one sleeps on my right, one on the left and one at my feet. When my husband was alive, we only had two cats. Usually then, only one cat would sleep with us. Apparently, they thought four was a crowd under those circumstances. If they'd been the type willing to sleep closer to each other, it wouldn't have been a problem, though.
