Can rabbits eat mayonnaise, and why?

Rabbits must never have mayonnaise. Egg, oil and fat are all harmful and indigestible 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.

Warning — what to watch for

Egg, oil and fat are all harmful and indigestible for rabbits.

If your rabbit has eaten mayonnaise, don’t wait for symptoms — contact your vet immediately, or call the Animal PoisonLine on 01202 509000 (24/7, UK). Signs of a problem can include vomiting, diarrhoea, drooling, lethargy, tremors or loss of appetite.
