I have been away over night and I got home and now my cat looks a lot smaller than when i left yesterday. I have a male cat in the house also and I am very worried that he may have killed the kittens, I don't see any kittens but she has a purple mark on her ear now and like I said she looks to be much smaller than she was... I am very worried???! Has anyone experienced this before? Her belly was much bigger and could feel the kittens moving now I cannot... What do I do?? Please respond as soon as possible!
