My cat ate Button Cactus — what to do
Step by step
- Take button cactus away and remove any plant material from your cat's mouth so they cannot eat more.
- Note roughly how much was eaten and when — this helps the vet judge the risk.
- Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
- Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and follow their advice.
- 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 button cactus — FAQ
Is button cactus poisonous to cats?
Yes — the ASPCA lists Button Cactus (Mammillaria prolifera) as mildly toxic to cats. 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.
How serious is it if my cat ate button cactus?
Button Cactus 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. 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. 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 button cactus well out of reach, or swap it for an ASPCA non-toxic plant — see the best cats-safe plants list.
