Our second cat, Mouse, had her kittens three days after Lavender. We have ten cute little kittens. Mouse climbed into the box with Lavender to have her kittens and surprisingly, Lavender helped her by licking the kittens clean and starting to nurse them. Now we have the two momma cats tag-teaming to keep the kittens nursed and warm.
You can see the cats are jammed into a small box. We tried to put them all into a larger box, but they kept taking the kittens back to this smaller one. I guess they know what they want!
