There are 3 three month olds who are big enough to play with the big girls now. As soon as I let them out to free range they head straight for the car hole. Why? There's nothing to eat in there but cat food, and that sits up on the work bench where they can't reach it. It's cute but they leave deposits that the puppy drags into the house. They spend most of their time in there hiding under the tractor. From what I couldn't tell you.
