Can rabbits eat fennel, and why?
Fennel, including the fronds, is a well-liked herb for rabbits.
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.
How to feed fennel to rabbits
- •How much: A small handful a few times a week as part of a varied mix of greens.
- •How often: An everyday option in sensible amounts, but rotate with other foods for variety. Sugary or starchy foods (including most fruit) should be a rare, thumbnail-sized treat, never a daily food.
- •Young pets: Baby rabbits (kits) have especially fragile digestion — new foods should only be introduced slowly as they grow, with vet guidance.
- •Preparation: Always wash fresh produce, remove any pips, stones, seeds, peel or tough skin where relevant, and serve it plain — never with salt, sugar, oil, butter or seasoning.
