Pet ingestion lookup
My cat ate Chives - what should I do?
Allium schoenoprasum
Potentially toxic
Contact your veterinarian or an animal poison-control resource now, especially if any amount was chewed or swallowed.
Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Vomiting, diarrhea, lethargy, pale gums, and elevated heart rate.
Escalation note
Ingestion can cause oxidative damage to red blood cells, potentially leading to hemolytic anemia. Please contact your veterinarian immediately if you suspect your cat has consumed chives.
What to watch for
Early: vomiting, drooling, decreased appetite. Later (hours to days): pale gums, weakness, lethargy, fast heart rate, panting, dark or bloody urine. Anemia signs can be slow to appear and easy to miss.
Time window
ASPCA notes that Heinz body changes can appear within 24 hours of ingestion, but clinical anemia signs may take several days to show. GI signs typically begin within a few hours.
When to call the vet
Call your vet or ASPCA Animal Poison Control (888-426-4435) right away if any chive material was eaten — even small ingestions warrant a call in cats. Do not wait for anemia signs, since they can lag the ingestion by a day or more.
What this means for your cat
Cats are the more sensitive species when it comes to Allium plants, and ASPCA lists chives as toxic. The N-propyl disulfide in the leaves damages red blood cells and can produce a delayed hemolytic anemia, which means a cat that seems fine the day of ingestion may still need monitoring for several days.
