I tryed separating them they was separated at one point but then the other cat was stealing the other ones baby’s then that’s when they both started to lay together I’ve tried putting them in the tub to give room the both just put the baby’s back in the crateIt is fine for them to share space and even to nurse each other’s kittens; however, they really need more room to stretch out to nurse.
Some people purchase a plastic kiddie pool and line it with towels. This gives lots of room for everyone. Kittens grow fast! Otherwise, cut and tape a couple of large boxes together for a larger space.
They look very content!
