Toxicology Profile
No Vomiting Reflex
Unlike most mammals, rabbits are anatomically incapable of vomiting. Any ingested toxin must travel the full length of the GI tract, extending exposure and increasing systemic absorption.
Gut Flora Disruption
Rabbits depend on cecal bacteria for up to 40% of their nutrition. Sugars and starches ferment rapidly in the cecum, producing gas and fatal dysbiosis (GI stasis) within hours.
Oxalate Accumulation
High-oxalate foods (spinach, beet greens, rhubarb) bind dietary calcium in the urinary tract, leading to kidney sludge and painful bladder stones with chronic feeding.

Clear FiltersCarrots
Carrots are not toxic to rabbits, but they are a sugary root vegetable, not a staple. Offer only a small piece occasionally — the cartoon image of rabbits living on carrots is a myth.
Cucumber
Cucumber is a genuinely safe, low-calorie vegetable for rabbits and makes an excellent hydrating treat. It contains no toxic compounds relevant to lagomorph physiology, and most rabbits find it highly palatable. Offered in sensible portions alongside unlimited hay, cucumber poses no meaningful health risk.
