Is Wolffia arrhiza toxic to cats?

Wolffia arrhiza

Mildly toxic to cats

Mildly. The ASPCA lists wolffia arrhiza 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. Wolffia arrhiza is not individually listed on the ASPCA Toxic and Non-Toxic Plants database, so a pet-safety claim cannot be confirmed; treat with caution and verify with a vet. The plant carries no recognised toxic principle (some Wolffia species are even eaten as a vegetable in parts of Asia), but dense surface films can shelter cyanobacteria, so water quality is the practical pet concern.

What to do if your cat ate wolffia arrhiza

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