    Remove any remaining plant material from the mouth and flush with milk, canned tuna or chicken broth.

    Call the veterinarian or a pet poison helpline for ongoing advice, you may be asked to monitor the cat or bring it in for treatment. This will be based on symptoms, comorbidities and the amount of plant ingested.

    If the cat is experiencing breathing difficulty, seek immediate veterinary care.

There is a higher incidence in kittens, due to their curious nature.
