Pet ingestion lookup
My cat ate Dock - what should I do?
Rumex sp.
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
Oral irritation, intense burning and irritation of the mouth, tongue and lips, excessive drooling, vomiting, and difficulty swallowing.
Escalation note
Symptoms are generally mild to moderate due to mechanical irritation from oxalate crystals. Please contact your veterinarian if your cat has ingested this plant.
What to watch for
Most likely in cats: drooling and oral irritation. Less common but worth knowing about: tremors and (rarely) signs of kidney involvement such as vomiting, lethargy, or change in urination after a larger ingestion.
Time window
ASPCA does not document precise onset for cats; soluble oxalate signs in domestic animals typically begin within hours of a meaningful ingestion.
When to call the vet
Call your vet if drooling or vomiting persists past a few hours, if your cat seems weak or wobbly (possible tremors), or if you observe changes in urination, refusal to eat, or any signs of dehydration.
What this means for your cat
Cats almost never browse on dock — the leaves are bitter and unpleasant — so most exposures stay mild. ASPCA lists Rumex species as toxic via soluble calcium oxalates, which can in theory cause kidney damage, though this is rare in cats at the small quantities they typically ingest.
