Is Star Cactus toxic to cats?

Astrophytum asterias

Mildly toxic to cats

Mildly. The ASPCA lists star 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. Astrophytum asterias is not individually listed in the ASPCA database, and the genus Astrophytum has no ASPCA entries, so we classify it conservatively. True cacti (Cactaceae) the ASPCA does list are non-toxic, and NC State Extension tags Astrophytum non-toxic to cats and dogs, so real-world poisoning risk is low; it is also spineless, avoiding the usual cactus spine injury. But without an ASPCA listing we won't assert it pet-safe — keep it out of reach and verify with your vet if a pet nibbles it.

What to do if your cat ate star cactus

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

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