Verdict

Chamomile (Matricaria chamomilla / Chamaemelum nobile) is listed as toxic to cats by the ASPCA. It contains volatile oils and sesquiterpene lactones that can cause vomiting, diarrhea, and skin irritation on contact, especially with the fresh plant or concentrated preparations. Diluted chamomile tea is sometimes used in tiny amounts as a mild calming aid, and severe reactions are uncommon, but it's not risk-free — cats with plant allergies (chamomile is in the same family as ragweed) may react more strongly.

Symptômes à surveiller

  • vomiting
  • diarrhea
  • loss of appetite
  • skin irritation or dermatitis on contact

Que faire

Keep the fresh plant out of reach. If a cat ingests a large amount or shows symptoms, contact a vet. Check with a vet before offering diluted tea, especially for cats with known plant sensitivities.
