but not the leaves from red/chinese/japanese maples. They have something in them that can be toxic to rabbits.Maple leaves of all colors. Even dried. As soon the they fell I raked a bunch of them, yellow, brown, in between, and set them in a sheltered place. Dosidoe munches on them even if they are3 not a preferred food. Of course if you have a maple tree you have maple seedlings. The seedling are a much desired food until summer time. Still freshly sprouted but something about summer and the rabbits turn off them.
