Squirrels are just Rats with better P.R.
I don't have a forested area, squirrels have to risk their lives to cross a highway and road to get to my yard. But one does.
The cat hates it too. I've been watching it. It stores nuts in my Pine trees /more

(not the same squirrel, I didn't have my camera)

@Rasta The PR doesn't work on everybody. I know someone who calls them "tree rats".
@TimWardCam True story, I've never had a bird feeder, but I have a neighbour that attracts rodents, and I put a feeder on a tree away from the house in the backyard and went around the house and returned to see it FULL all around the feeder. OF RATS!!! and I took it down and never had a bird feeder again
