Is Welsh Poppy toxic to cats?

Yes — welsh poppy is toxic to cats according to the ASPCA. Keep it well away from any cat that chews plants; reactions can be significant. Contains isoquinoline alkaloids — magnoflorine is the major constituent in all plant parts, and mecambrine is also present. Although the alkaloid profile differs from opium poppy, all Papaveraceae poppies are considered toxic to dogs and cats, with potential symptoms including vomiting, sedation, respiratory depression, and incoordination. Contact a vet immediately if ingestion is suspected.

Contact a vet immediately if ingestion is suspected. Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your cat has had access to welsh poppy.

Stay calm. Remove any plant from your cat's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.
