Probably something best NOT thought about. They and/or cats would take over the world.
I shudder to think. We tried everything we could think of to discourage them from the feeders (the squirrels that is) but they will ALWAYS find a way.
My first thought was there was a nose at the top and couldn't figure out what it was, maybe a hedgehog, but that didn't make sense. Now I can see the squirrel upside down with a puffed out tail. - Margy
