About 3 years ago I watched several baby squirrels pull pieces of bark from a tree and then play catch with them between themselves. The used the bark like any kid playing with a ball. This was the first time I ever say baby critters play with homemade toys.
If you’d taken video of that and posted it on the u-toobz, you’d probably be a zillionaire, or something like that.
(I, for one, would love to see baby squirrels at play)
