My cat had kittens a week ago today and this is her second litter. She’s on the front porch in a box lined with towels and blankets. Well today I went out to check on them and she moved three under this game board thing right next to the porch but left one in the box. And the one she left is breathing heavily and sneezing a lot. Should I move the kittens back or should I take the one she left away from the rest and give her formula?
