Thank you everyone! I'll have pics up as soon as I can.
This morning I found Medusa bleeding around the house. We took her into the vets and found a kitten that was still inside of her. So they are going to have surgery plus she'll get spayed. They told us that we may be able to pick her up later on tonight since she is nursing. So I'm hoping she'll be okay. So I'm taking care of the 3 babies while she's there.
A reason why she wasn't spayed in the first place is she had a social problem and she was given too young away from her momma. So we've raised her, she got to the point when she hit a certain age that we couldn't do anything with her except when she would get in heat. She liked to escape from our house and we wouldn't see her for days so we got another kitten to help her get socialized. We still believe she still has some of it, but I'm really glad that she has the motherly instinct because most the cats that I had didn't and would have killed them the instant they saw them.
