Negotiating with squirrels is pointless. So, I try to baffle them instead. Yet, they still find a way to reach the bird feeders. I have installed a squirrel baffle to the recommended 5 feet. It is apparently not so baffling that they can't climb up three feet on the bird feeder pole, leap 3 feet through the air on to the lowest hanging feeder and eat to their furry little heart's content.
My solution: Poodle. Louis loves to chase the squirrels and gets wild eyed when I even say the word "squirrel." Now, if a squirrel is on the bird feeders, I go to the door, whisper "squirrel!" with some urgency and release the snarling squirrel hunter. Part of the fun is that Louis is absolutely determined to catch one. He puts his head down and runs with all his might after the little bastards. It's pretty cute. He hasn't caught one yet, and I honestly don't know what would happen if he did. I would probably scream like a girl, then try to figure it out. Good in a crisis. That's me.
