Is Sieber's Crocus toxic to cats?

Crocus sieberi

Mildly toxic to cats

Mildly. The ASPCA lists sieber's crocus as mildly toxic to cats — a chewing cat typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. True spring Crocus (Iridaceae) is listed by the Pet Poison Helpline as moderately toxic to dogs and cats, causing drooling, vomiting, diarrhea, and loss of appetite if ingested. It is distinct from and far less dangerous than Colchicum ('autumn crocus', Colchicaceae), which causes severe organ failure. ASPCA does not individually list Crocus sieberi, but categorizes spring Crocus spp. as causing mild GI signs.

What to do if your cat ate sieber's crocus

  1. Remove any plant material from your cat's mouth and move sieber's crocus out of reach.
  2. Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
  3. Do not induce vomiting unless a vet or poison-control specialist instructs you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
  5. Bring a leaf or photo of sieber's crocus to the appointment so it can be treated correctly.

General guidance, not veterinary advice. If you think your cat has eaten sieber's crocus, contact your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 — do not wait for symptoms to worsen.
