They don't eat that stuff. In fact, if they're starving, they won't eat it. Berries and nuts, that
will attract them. The fleshy parts of new leaflets and maple wings, that sort of thing.
Now, rabbits, that's a different story. Give them lettuce any day. If the greens are very dark, squirrels may sometimes eat them.
I was thinking about the chipmunks a bit ago. In my domain here, it's the foxes that dig out the fences, in fact, chasing the chipmunks. The foxes don't scale the fences well and can't climb the way raccoons do. The chipmunks just go through them.
If the chipmunks had smiles on their faces, it's probably because they heard about their upcoming move to the west where their relatives are enjoying life to the fullest. Maybe they can catch a ride with Charlie's geese.
