My cat ate Sea Pea — what to do
Step by step
- Take sea pea 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 sea pea — FAQ
Is sea pea poisonous to cats?
Yes — the ASPCA lists Sea Pea (Lathyrus japonicus) as toxic to cats. The entire Lathyrus genus contains the neurotoxic amino acid beta-aminopropionitrile (BAPN), particularly concentrated in the seeds. The ASPCA lists Lathyrus (sweet pea) as toxic to horses (aminoproprionitrite causing weakness, lethargy, tremors, seizures, and possible death); effects in dogs and cats are generally gastrointestinal at low doses but neurological damage (lathyrism) is possible with repeated or large-dose ingestion. Treat all Lathyrus as toxic to pets and contact a vet or the ASPCA Animal Poison Control Center (888-426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK) if ingestion occurs.
How serious is it if my cat ate sea pea?
Sea Pea is toxic to cats and reactions can be significant, so treat any ingestion as urgent. Call your vet, or (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK, straight away rather than waiting to see if symptoms develop.
What symptoms should I watch for?
Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy. The entire Lathyrus genus contains the neurotoxic amino acid beta-aminopropionitrile (BAPN), particularly concentrated in the seeds. The ASPCA lists Lathyrus (sweet pea) as toxic to horses (aminoproprionitrite causing weakness, lethargy, tremors, seizures, and possible death); effects in dogs and cats are generally gastrointestinal at low doses but neurological damage (lathyrism) is possible with repeated or large-dose ingestion. Treat all Lathyrus as toxic to pets and contact a vet or the ASPCA Animal Poison Control Center (888-426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK) if ingestion occurs. 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?
Keep sea pea well out of reach, or swap it for an ASPCA non-toxic plant — see the best cats-safe plants list.
Type any plant to see what the ASPCA says about it and your cat.
