The wild cottontail rabbits are eating the rubellia bushes that I use for tortoise food. I have been to the hardware store and found several repellant sprays but none of them sound very safe for eating. Looked at blood meal and not sure if that is safe either. The only thread I could find talks about solar powered sound emitting repellers that apparently aren't effective. Help please. What do you use to keep rabbits away that won't harm your torts????
