I have 2 female cats, and one just recently had kittens. Sje cares for them well, and has had no problems. However, just today, my other female cat has started to shiw great interset in them; she has started to follow you around if you are holding a kitten, and she has started to climb into the box with the mother & kittens, and trying to cuddle up with them. We think she may be pregnant herself...is she just feeling maternal or does she actually think the kittnes are hers?
