Hi! My 2 year old cat Baby had her first litter of kittens on March 11th, I was & am super happy but the whole birth went well she had 4! After she finished & I got to get a good look at them I noticed one is alot larger than the others his belly when born was the size of a golf ball, I decided to wait to see if he got any larger, he has, he's now the size of a tennis ball, were taking him to the vet soon (She only comes in once a month small town) I don't understand what could be causing this, all the others are fine, he eats just fine & is okay when picked up (I tell everyone not to move him) besides when he rolls on his back he can't roll back over, I'm afraid it may be a tumor? Has anyone heard of this before?
