Rabbits
Rabbits are strict hindgut-fermenting herbivores; their delicate gut flora can be fatally disrupted by sugars, starches, and fats.

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 FiltersAlmonds
Almonds are not suitable for rabbits and should be treated with significant caution. Their high fat and protein content is incompatible with the rabbit's herbivorous digestive physiology, and even small quantities can trigger gastrointestinal upset or dangerous GI stasis. While almonds do not contain a single acutely lethal toxin in the way grapes affect dogs, the cumulative metabolic burden they place on a rabbit makes them an inappropriate food entirely.
Cherries
Fresh cherry flesh is not acutely toxic to rabbits in small amounts, but the pits, stems, and leaves contain cyanogenic glycosides that can cause serious harm. The fruit itself is very high in sugar, which poses a real risk to a rabbit's sensitive digestive and metabolic systems. Cherries should be treated as an occasional, strictly portioned treat — never a dietary staple.
Carrots
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.
Cinnamon
Cinnamon is not acutely toxic to rabbits, but it carries real caution flags that make routine feeding unwise. The volatile compounds in cinnamon — particularly cinnamaldehyde and coumarin — can irritate a rabbit's sensitive gastrointestinal tract and mucous membranes, and coumarin carries hepatotoxic potential with repeated exposure. Small, occasional contact is unlikely to cause serious harm, but cinnamon offers no nutritional benefit a rabbit cannot obtain from safer foods, so there is no compelling reason to offer it.
Pears
Ripe pear flesh is not toxic to rabbits, but the high sugar content makes it a treat that must be strictly limited. The seeds and core pose a genuine hazard due to trace amygdalin (a cyanogenic glycoside), so those parts should never be offered. When given correctly — small pieces of seedless flesh, infrequently — pears are a safe occasional reward rather than a dietary staple.
Ginger
Fresh or dried ginger is not classically toxic to rabbits, but its potent volatile oils and pungent compounds make it inappropriate as a regular dietary item. Small incidental amounts are unlikely to cause serious harm, yet rabbits' highly sensitive gastrointestinal tracts can react badly to even modest quantities. Owners should treat ginger as an occasional, tiny treat at most — not a staple herb.
