I've certainly had three that were excellent even with tiny kittens. The others I never found out because I didn't want to take the risk.

That said, my girl who had the kittens two days ago wanted to have them in the stud pen - followed me out there, pushed her way in, ate all his food (she does that at every opportunity so nothing new) and then got into his igloo and looked like she was settling down ready to have them right there. I drew the line at that!
