I dont have squirrels, I have rabbits. My old neighborhood had squirrels and feeding them can make them friendlier. We used to have them come right up to us if you wanted them that close or not. My cousin's dog eat a piece of a dried corn cob that a squirrel left in their yard and cost them 2000.00 to get it out of the dogs stomach, the dog nearly died. So you might want to make sure you only use whole cobs stuck to a long nail so the only eat the kernals and dont run off with them.
