Is Button Cactus toxic to cats?

Mammillaria prolifera

Mildly toxic to cats

Mildly. The ASPCA lists button cactus 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. Mammillaria prolifera is not individually listed on the ASPCA toxic or non-toxic plant database, so its status is unconfirmed; treat with caution and verify with a vet. No toxic principle is documented for the genus, but the spines are a physical hazard. The small red fruits are edible to humans, yet that does not establish ASPCA pet safety, so keep the plant away from cats and dogs.

What to do if your cat ate button cactus

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

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