Can rabbits eat ketchup, and why?
Rabbits must never have ketchup. Salt, sugar, onion and garlic are all harmful to 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.

Salt, sugar, onion and garlic are all harmful to rabbits.
