Cherry pits, stems, and leaves contain cyanogenic glycosides that convert to cyanide when chewed or digested. Because cats are so much smaller than dogs or humans, a single chewed cherry pit can release enough cyanide to cause serious symptoms.
The safest approach is to keep cherries away from cats entirely, since reliably removing every trace of pit, stem, and leaf from a serving is difficult. If a cat swallows any part of a cherry, treat it as a medical emergency.
Contact your veterinarian or a pet poison control hotline immediately — this is considered a medical emergency. Watch for dilated pupils, panting, difficulty breathing, vomiting, or dark red gums, which can signal cyanide poisoning.
No. Maraschino cherries are soaked in sugary syrup and preserved with additives, and they may still have stems attached.
