Is Concrete Leaf toxic to cats?

Titanopsis calcarea

Mildly toxic to cats

Mildly. The ASPCA lists concrete leaf 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. Titanopsis calcarea is not individually listed on the ASPCA toxic/non-toxic plant database, and no other Titanopsis species is listed (the ASPCA "Living Stones" entry is the different genus Lithops). No specific toxic principle is reported for the Aizoaceae family, so the risk is considered low, but because the genus is not confirmed safe by ASPCA we treat it conservatively as mildly toxic - keep out of reach and verify with your vet before allowing pet access.

What to do if your cat ate concrete leaf

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

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