No squirrels in our house either, as they may have rabies, poop on the floor, etc.
They do tricks? Do you teach them or are they that smart?
No, but they seem really aware of what sort of antics draw the most peanuts. Sometimes I encourage them by saying: “Do tricks!” and they don’t obey, they just seem to know what you want them to do based on past rewards. (Isn’t that strange?????)
When our family first moved to Colorado we went for a scenic drive on (I think) Berthoud Pass. There was one place we pulled over where obviously a lot of other people had pulled over (this was in the early 1970s) and there was a sign saying don’t feed the ground squirrels. We got out to look around and A SMALL ARMY of ground squirrels came running up and - they weren’t being aggressive, but they were jumping up and down and capering all around. My mom was scared. (We gave them some food so they wouldn’t attack.)
