My cat ate Starry Rosinweed — what to do

Step by step

  1. Take starry rosinweed away and remove any plant material from your cat's mouth so they cannot eat more.
  2. Note roughly how much was eaten and when — this helps the vet judge the risk.
  3. Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
  4. Call your vet, or a poison-control line — (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK. Both charge a consultation fee. Follow their advice.
  5. Watch for drooling, pawing at the mouth, vomiting, loss of appetite, or lethargy, and bring a leaf or photo to the appointment.

This is general guidance, not veterinary advice. Pets vary, and a reaction may be to soil, fertiliser, or pesticide as well as the plant. When in doubt, call your vet — or the ASPCA Animal Poison Control Center on (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK.

My cat ate starry rosinweed — FAQ

Is starry rosinweed poisonous to cats?

Yes — Starry Rosinweed (Silphium asteriscus) is regarded as mildly toxic to cats, based on genus- and family-level toxicity data. Silphium asteriscus is not individually listed in the ASPCA Toxic and Non-Toxic Plant database. The genus contains resinous compounds (silphiodiene sesquiterpenes) whose pet safety is unconfirmed; classified as mildly-toxic out of caution — keep pets away and consult a vet if ingestion is suspected.

How serious is it if my cat ate starry rosinweed?

Starry Rosinweed is mildly toxic, so most cats get short-lived mouth irritation, drooling, and vomiting rather than a life-threatening reaction. It is still worth a vet call to be safe, especially if your cat ate a lot or symptoms persist.

What symptoms should I watch for?

Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy. Silphium asteriscus is not individually listed in the ASPCA Toxic and Non-Toxic Plant database. The genus contains resinous compounds (silphiodiene sesquiterpenes) whose pet safety is unconfirmed; classified as mildly-toxic out of caution — keep pets away and consult a vet if ingestion is suspected. Any worsening or persistent symptoms warrant an immediate vet visit.

Should I make my cat vomit?

No — do not induce vomiting unless a vet or a poison-control specialist specifically tells you to. The wrong action can make things worse. Call your vet, or (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK, and follow professional advice.

How do I stop this happening again?

Keep starry rosinweed well out of reach, or swap it for an ASPCA non-toxic plant — see the best cats-safe plants list.
