Is Blue Lyme Grass toxic to cats?

Leymus arenarius 'Blue Dune'

Mildly toxic to cats

Mildly. The ASPCA lists blue lyme grass 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. Leymus arenarius is not individually listed in the ASPCA Toxic and Non-Toxic Plants database, so a pet-safe status cannot be confirmed; treat with caution and verify with a vet. As with grasses generally, eating large amounts may cause mild gastrointestinal upset in cats and dogs.

What to do if your cat ate blue lyme grass

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

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