Can rabbits eat corn on the cob, and why?
Corn on the cob is not suitable for rabbits. Sweetcorn is too starchy and the cob and kernel hulls can cause dangerous blockages.
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.
