Is Bitter Vetch toxic to cats?

Lathyrus linifolius

Mildly toxic to cats

Mildly. The ASPCA lists bitter vetch 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. The Lathyrus genus contains toxic amino acids (lathyrogens, including beta-aminopropionitrile/BAPN) concentrated especially in the seeds. ASPCA lists Lathyrus latifolius (perennial sweet pea) as non-toxic to cats and dogs but toxic to horses. L. linifolius is expected to share this profile; large seed ingestion could cause gastrointestinal upset or, in horses, neurological signs (lathyrism). Pets should be prevented from grazing the seeds.

What to do if your cat ate bitter vetch

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

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