Why is avocado 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.

Avocado contains persin, a fungicidal toxin that rabbits are unusually sensitive to — Merck lists rabbits explicitly among susceptible species. Effects can include heart-muscle damage and, in lactating animals, mastitis. The high fat content also upsets a rabbit's gut, which depends on low-fat, high-fiber food.
