My cat ate Downy Painted Cup — what to do

Step by step

  1. Take downy painted cup 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 downy painted cup — FAQ

Is downy painted cup poisonous to cats?

Yes — Downy Painted Cup (Castilleja sessiliflora) is regarded as mildly toxic to cats, based on genus- and family-level toxicity data. Castilleja sessiliflora is a secondary selenium accumulator: in high-selenium soils it concentrates selenium in leaf and root tissue to potentially toxic levels. ASPCA does not list the genus as definitively safe; ingestion may cause selenium-related symptoms (lethargy, hair loss, hoof/nail changes in livestock, gastrointestinal upset in dogs and cats). Keep pets from grazing this plant.

How serious is it if my cat ate downy painted cup?

Downy Painted Cup 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. Castilleja sessiliflora is a secondary selenium accumulator: in high-selenium soils it concentrates selenium in leaf and root tissue to potentially toxic levels. ASPCA does not list the genus as definitively safe; ingestion may cause selenium-related symptoms (lethargy, hair loss, hoof/nail changes in livestock, gastrointestinal upset in dogs and cats). Keep pets from grazing this plant. 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 downy painted cup well out of reach, or swap it for an ASPCA non-toxic plant — see the best cats-safe plants list.
