Well, according to Animal Planet there is and it is today, January 21st, and it was started by a wildlife rehabilitator from Asheville, North Carolina (which is just about an hour and a half drive from me) in 2001.
You learn something new every day!
Anyway, since it is indeed the day to honor these cute little tree rats (and also because this was a good excuse for me to take another break from cleaning house), I'm sharing my most recent photo of the Darlings ''appreciating" the one who feasts daily on the berries of the holly tree beside my bedroom window...
Happy Squirrel Day! ;)
