Can Rabbits eat ...?
Food safety index

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 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 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.
