Is Azolla filiculoides toxic to cats?

Azolla filiculoides

Mildly toxic to cats

Mildly. The ASPCA lists azolla filiculoides 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. Azolla filiculoides 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. Its symbiotic cyanobacterium has largely lost the genes for classic cyanotoxins, but as a cyanobacteria-hosting floating mat it can degrade water quality, so a pet drinking from an Azolla-covered pond is the practical hazard to monitor.

What to do if your cat ate azolla filiculoides

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

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