What height should I build a fence to keep out Raccoons?

to keep the raccoons out of your pound use a lid to keep them from getting over the pound (because they are awesome climbers). you can even use an old Screen to put from side to side, and make shure they don't have any way of getting over under or threw the fence and screen (because if you find a hole then you may have to fix it). after the raccoons have gone you can take of the screen (as long as they haven't found a new food source near by).
