Not really frustrated. The birds make a bigger mess and the squirrels clean some of it. I can't hate on squirrels, being a good Dawg and all.
I just have to accept the squirrels, too. In fact, I am more fascinated watching squirrels, sometimes. I'll have to dig up a pic from a few years ago showing a Ninja, fucking Mission Impossible, Tom Cruise, MI, DoubleO, Batfoot, hanging upside down, marauding, assassin ...
I went to find it.
