My cat ate Common Bird's-foot Trefoil — what to do
Step by step
- Take common bird's-foot trefoil 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 common bird's-foot trefoil — FAQ
Is common bird's-foot trefoil poisonous to cats?
Yes — the ASPCA lists Common Bird's-foot Trefoil (Lotus corniculatus) as mildly toxic to cats. Contains cyanogenic glycosides (principally lotaustralin) that release hydrogen cyanide when plant tissue is damaged; large quantities can cause vomiting, lethargy, and respiratory distress in dogs and cats. Not listed individually on the ASPCA database; classified as mildly toxic based on confirmed cyanogenic glycoside content.
How serious is it if my cat ate common bird's-foot trefoil?
Common Bird's-foot Trefoil 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. Contains cyanogenic glycosides (principally lotaustralin) that release hydrogen cyanide when plant tissue is damaged; large quantities can cause vomiting, lethargy, and respiratory distress in dogs and cats. Not listed individually on the ASPCA database; classified as mildly toxic based on confirmed cyanogenic glycoside content. 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 common bird's-foot trefoil well out of reach, or swap it for an ASPCA non-toxic plant — see the best cats-safe plants list.
