Do rabbits eat rose bush leaves?

Yes, rabbits in the wild will readily eat roses, both the flowers and leaves of the plant. In fact rose buds are particularly sweet and succulent, and even humans occasionally enjoy them. However, the leaves are somewhat more fibrous than many other plants and are most likely harder for a rabbit to digest.

Since there are several more easily digested and nutritious plants and vegetables readily available, rose leaves are lower on the list of items one would regularly feed to a pet rabbit. If yours happens to like them, there's no reason why the occasional sprig of fresh leaves wouldn't be a welcome addition to their diet.
