My female cat named BABY is very pregnant and isn't want to play. You can see the kittens movement with no problems. She licks her belly and her hind legs a lot, but I do not see any discharge from her at all. She saw the vet three weeks ago to the day. My question is how much longer do you think she has?? She hasn't started beating yet but she has been more friendlier and sleeping next to me. Her nipples are also a little crusty but I haven't seen any milk come from her breasts only that they seem to be getting full. Please help. This is my first time with a pregnant cat.
