I have a pregnant long haired tortoise shell cat. Last night she went into labour, but all that she delivered was a weird fleshy mass, about 2" in diametre. She has been calm and comfortable ever since, resting in her box, but I can't figure out what is going on. This doesn't fit the description of anything I've read on cats giving birth. This pregnancy is the first for both myself and my cat. Does anyone have any insight?
