The kits are 15 days old today, and although they're growing beautifully (read: fat little guts!) And are hopping around when I take them out, they're lazy buggers and are very content to sleep all day and night otherwise. They've shown no interest in getting out of the nest themselves. It's a beautiful nest built at the back of a carrier, behind a deep bank of hay so it wouldn't be super easy to get out of, but they don't appear to be trying. I know that's not such a problem for a few more days yet, but they are gettig FILTHY and I'm worried about infections and the like. How long do I give them before they get boooted from the nest? Shoukd I be cleaning the little grubsters?
