These pesky squirrels won't give up

I moved the hanging bird feeder, put it on a shepard hook, darn if they didn't get to it this morning. So I went out there and put some oil on the hook, I'll tell you that if I had some black grease I would of put it on there. It was funny watching the squirrel this afternoon, he acted like he wanted to jump from one of the branches he sat there looking at the feeder for the longest time, finally he went to the ground. But he was looking all over the place, he knew the kitten was lurking around somewhere and with every couple steps he would sit up and look around. Finally made it to the shepard hook, but didn't get up very far he kept sliding down. So its a temporary solution.
