aggieAXO,
I just didn't wait at one point and took it to the vet. She thought perhaps the placenta might be in there but she wasn't sure. I never saw any "green" things come out, which she said would be an indication that it came out. Anyway, she gave it some shot just in case. It's still a fat cat and now it's scared of me, but at least i can be sure it's ok. Thank you for your help

You're really kind.
