My cat ate Golden Ragwort - what should I do?
Senecio species
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
Drooling, vomiting, diarrhea, lethargy, and potential liver damage.
Escalation note
Ingestion can lead to serious systemic health issues due to alkaloids. Please contact your veterinarian immediately if you suspect your cat has consumed any part of this plant.
What to watch for
Early signs are easy to miss: weight loss, drowsiness, weakness, and yawning. As liver damage progresses, expect jaundice (yellow gums or eye whites), incoordination, and neurological changes such as aimless walking.
Time window
Liver damage from pyrrolizidine alkaloids is cumulative; clinical signs may not appear for days to weeks after ingestion as injury progresses.
When to call the vet
Call right away for any known ingestion, even if your cat seems fine. Once jaundice, weakness, or behavior changes appear, treat it as urgent — the prognosis worsens once clinical signs are visible.
What this means for your cat
Golden Ragwort is one of the more dangerous toxic plants for cats — pyrrolizidine alkaloids cause cumulative liver damage, and even small repeated nibbles can add up. Signs may not appear until liver injury is already substantial, so any known ingestion warrants prompt veterinary contact.
