Gosh you are so lucky, I would love to have a squirrell in my back garden , we donot have them in NZ, I have only ever seen one when I was in USA, and to me they are just simply beautiful little creatures.

I can imagine they can be a bit annoying , but then so can birds nesting in the roof and scratching about, but we have learned to tolerate those and enjoy the beauty of every living creature, I hope you can find it in your heart to do the same.
