Squirrels can be very confrontational, there’s one of my backyard that I have exchanged expletives with but so far no fight yet. I cut down his favorite tree so he doesn’t come around as much anymore.
Perhaps you should have found out if your squirrel is, by any chance, a MUSLIM.
We have a golf course across the street so.......squirrels! I’ve had them come after me when I gave them crap. Hubby says I’m nuts that they don’t do that but I swear it. Had one come across a tree limb and jump on top of our patio after me. Lol
