Cats should generally not eat cherries. While the flesh of ripe cherries is not toxic to cats, the stems, leaves, and pits contain cyanide compounds which are highly toxic and can cause serious poisoning. Ingesting cherry pits can also pose a choking hazard and risk of intestinal blockage. Symptoms of cyanide poisoning in cats include difficulty breathing, dilated pupils, vomiting, diarrhea, and potentially fatal outcomes. Due to these risks, it is safest to avoid feeding cherries to cats altogether and keep cherries out of their reach.
