Is Swamp Loosestrife toxic to cats?

Decodon verticillatus

Mildly toxic to cats

Mildly. The ASPCA lists swamp loosestrife 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. Decodon verticillatus is not listed on the ASPCA toxic-plant database and no documented pet toxicity cases are reported. However, it belongs to Lythraceae and no confirmed safety data exists for cats and dogs, so it is classified as mildly-toxic as a precaution. Keep pets away from plants in and around water features for general safety.

What to do if your cat ate swamp loosestrife

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

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