I spotted our stripe-y tailed neighbor again today and trained a pair of binoculars on the grey lump that I keep posted by the back door now. Our gigantic he-coon is apparently a recent MamaCoon. She wasn't sleeping, but jerking her head strangely and doing an odd scrabble with her front paws. Turns out she was trying to simultaneously clean a baby and keep it from falling out of the tree.
There's a big hole in the tree right at the junction of that branch she was sleeping on the other day, which I'd previously missed, and apparently a whole raccoon family living inside of it.
The thought of watching baby raccoons growing up is just as thrilling as the idea of lemurs!
