Can rabbits eat seaweed, and why?
Seaweed is best avoided for rabbits. Not part of a natural herbivore diet and often high in salt and minerals; stick to leafy greens.
Rabbits are herbivores: roughly 85% of their diet should be good-quality hay or grass, plus a daily handful of leafy greens, with only small amounts of other veg and tiny occasional fruit. They have a sensitive hindgut that depends on constant fibre — sudden changes, sugar or starch can trigger dangerous gut stasis and bloat.
Warning — what to watch for
Not part of a natural herbivore diet and often high in salt and minerals; stick to leafy greens.
