Humulus lupulus

Toxic to cats

Yes — humulus lupulus is toxic to cats according to the ASPCA. Keep it well away from any cat that chews plants; reactions can be significant. This classification follows the ASPCA Toxic and Non-Toxic Plant List. The ASPCA lists hops (Humulus lupulus) as toxic to dogs. Ingestion of hops — fresh, pellet, or spent brewing material — can trigger a malignant hyperthermia-like reaction with panting, dangerously high body temperature, vomiting, agitation, rapid heart rate, seizures and death. Keep all plant material and spent hops well away from dogs; contact a vet or ASPCA Poison Control immediately on ingestion.

What to do if your cat ate humulus lupulus

  1. Remove any plant material from your cat's mouth and move humulus lupulus 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 humulus lupulus to the appointment so it can be treated correctly.
