Omg.... is it the breed? I have a mama the same thing is happening. (Not trying to post on your thread to make it mine) but check this out... Lily same color as your cat Lynx Point had one baby on Sunday 48 hours later another one and I can see more in her tummy. I'm waiting to take her to the vet per the advice read in this post. She is content and taking care of them so I'm not too worried.
