Answer: Squirrels can go attack the wildest things sometimes. I've never heard of squirrels attacking mulberry leaves as they emerge. I'd think any of the commercially available repellents such as Ropel and Hinder may be work a try to stop their bizarre activity. These should be available at local garden centers. I would guess they will stop once other food becomes available. You could try to lure they away with a squirrel feeder, but that may just encourage them to stay in the neighborhood more. A good cat might also be worth a try!
