Are brussels sprouts 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.

One of the most fermentable vegetables on the list. Many rabbit keepers skip them entirely; if you try them, the introduction matters more than the quantity.

How many brussels sprouts can a rabbit have?

Half a small sprout as a test, then only if 24 hours of droppings and behavior stay normal.

How to serve it

If gassy, switch to cilantro, romaine or basil — equally loved, gentler.
