Something is eating my plants!

Something or someone has been eating all my squash plants AND my pepper plants. They seem to eat some of the leaves, but not all of them. Some of the leaves they just leave beside the plant. I have seen no woodchucks nearby but I have seen rabbits. More than one person swears that a rabbit will not do this. I don't believe it. I have put mouse traps and human hair around them. It doesn't help. Any ideas would be welcome. Thank you.
