as u can tell from all my other posts i am new to all of this...i have had kittens/cats in the past but never a new litter.......i have noticed when the kittens are standing , from a side view i see a pouch in their lower abdomen area...its like a bubble....its not solid...its more like really soft....skin hanging....its not wrinkled but its also not solid full...this is soo hard to explain...can ya tell? lol...kinda like most mothers get right after having a baby....some of us are lucky and dont get that but anyhow...im just wondering if that is normal? are they not eating enough???
