Can rabbits eat breakfast cereal, and why?
Breakfast cereal is sugary and starchy and unsuitable for rabbits. Sugar and starch can cause serious digestive upset.
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
Sugar and starch can cause serious digestive upset.
