My cat ate Rat Tail Cactus — what to do
Step by step
- Take rat tail 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 a poison-control line — (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK. Both charge a consultation fee. 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 in the US, or Animal PoisonLine on 01202 509 000 in the UK.
My cat ate rat tail cactus — FAQ
Is rat tail cactus poisonous to cats?
Yes — Rat Tail Cactus (Disocactus flagelliformis) is regarded as mildly toxic to cats, based on genus- and family-level toxicity data. Disocactus flagelliformis is not individually listed in the ASPCA toxic or non-toxic plant database, and no Disocactus species is listed — the non-toxic cacti ASPCA does name (e.g. mistletoe cactus Rhipsalis, old man cactus Cephalocereus, Christmas cactus Schlumbergera) are different genera, so safety cannot be assumed; verify with your vet before allowing pet access. Regardless of ingestion risk, the fine bristly spines are a physical hazard to curious pets, so keep this cactus out of reach.
How serious is it if my cat ate rat tail cactus?
Rat Tail 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. Disocactus flagelliformis is not individually listed in the ASPCA toxic or non-toxic plant database, and no Disocactus species is listed — the non-toxic cacti ASPCA does name (e.g. mistletoe cactus Rhipsalis, old man cactus Cephalocereus, Christmas cactus Schlumbergera) are different genera, so safety cannot be assumed; verify with your vet before allowing pet access. Regardless of ingestion risk, the fine bristly spines are a physical hazard to curious pets, so keep this cactus out of reach. 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 a poison-control specialist specifically tells you to. The wrong action can make things worse. Call your vet, or (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK, and follow professional advice.
How do I stop this happening again?
