This Is New
So far, we have had three cats have their kittens in the calving shed, but new this year is the "community cafe." They just put them all in one pile and then go over and nurse them. The kittens just find an opening and latch on to whatever is available.
Maybe it's easier to protect them that way with three moms around, but it's the first time I've seen this. I said the same thing when my wife and I were having kids. What's one more going to hurt?
