on cats because they are litter animals, you can just cut the cord if the placenta is still inside, it is already detached when the kitten is born. the milk will come in before the actual contractions start so the kittens can nurse immediately. So far I had now big problems with small cats, a little problem with first tiny tiny siamese and 5 kittens, her belly was on the floor and I had to clean her bottom for some time. She fatigued near the end and I pulled one kitten while she recovered her energy. That was all.
