My cat ate Liquorice — what to do

Step by step

  1. Take liquorice 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 the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and 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.

My cat ate liquorice — FAQ

Is liquorice poisonous to cats?

Yes — the ASPCA lists Liquorice (Glycyrrhiza glabra) as mildly toxic to cats. Glycyrrhiza glabra is not listed as toxic by ASPCA for dogs or cats. However, glycyrrhizin, the key active compound in the root, can be harmful in large or repeated doses to both humans (causing pseudohyperaldosteronism — sodium retention, potassium loss, hypertension) and pets. Casual contact or small incidental ingestion is low-risk, but concentrated root preparations or large quantities should be kept away from pets, particularly those with cardiac or renal conditions.

How serious is it if my cat ate liquorice?

Liquorice 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. Glycyrrhiza glabra is not listed as toxic by ASPCA for dogs or cats. However, glycyrrhizin, the key active compound in the root, can be harmful in large or repeated doses to both humans (causing pseudohyperaldosteronism — sodium retention, potassium loss, hypertension) and pets. Casual contact or small incidental ingestion is low-risk, but concentrated root preparations or large quantities should be kept away from pets, particularly those with cardiac or renal conditions. 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 the ASPCA Animal Poison Control Center specifically tells you to. The wrong action can make things worse. Call (888) 426-4435 and follow professional advice.

How do I stop this happening again?

Keep liquorice well out of reach, or swap it for an ASPCA non-toxic plant — see the best cats-safe plants list.
