Is azolla pinnata safe for cats and dogs?
Use caution. Azolla pinnata is on the mildly-toxic side of the ASPCA list. Most ingestions are short-lived but unpleasant for the pet; the cost-free fix is a placement they can't reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. Azolla pinnata is not individually listed on the ASPCA Toxic and Non-Toxic Plants database, so its pet status is not confirmed; treat with caution and verify with a vet. Note that wild-collected Azolla mats can harbour cyanobacteria (blue-green algae) and accumulated contaminants, which are a genuine ingestion hazard for pets and livestock.
| Pet | Toxic? | Per ASPCA |
|---|---|---|
| Cats | Yes (mild) | Mildly toxic to pets |
| Dogs | Yes (mild) | Mildly toxic to pets |
