Are collard greens good or bad for rabbits?

A rabbit’s diet is a pyramid with hay at the base: roughly 80% grass hay, 10–15% leafy greens, and a small daily pellet portion (House Rabbit Society model). Anything outside that pyramid is a treat — and sugar is the enemy of the gut flora that keeps a rabbit alive.

Nutrient-dense but fermentable. Same rule: slow introduction, one new food at a time, watch the gut.
