Hi, my cat has just today given birth to 3 healthy full term kittens who are all feeding well, however she also gave birth to a fourth kitten who appeared rather premature. It was smaller with shorter limbs, no hair at all and red/purple skin. It was born in the sack with a mess of placenta attatched. It seemed to wriggle for a minute or two but then passed away. I'm wondering if this kitten was just under developed or whether it could be from a second litter? She escaped out the front door at about 3 weeks pregnant which is why i am wondering this. It does feel like there are possibly still kittens in her belly. Any help would be much appreciated. I have called the vet but he can't come tonight and i dont want to move her and the kittens yet to take them to the surgery as they are only a few hours old. He has told me things to look out for the could be warning signs of a problem but at the moment she is very content and happily feeding her babies. She is no longer contracting or pushing or showing any other signs of being in labour still. I'm still so very worried though so any advice would be great. Thanks in advance.
