Is humped bladderwort safe for cats and dogs?
Not entirely — humped bladderwort is mildly toxic to cats and dogs. It rarely causes serious harm, but chewing it triggers real discomfort, so keep it out of a pet's 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. Utricularia is not individually listed by the ASPCA, so its status for cats and dogs is unconfirmed; treat with caution and verify with a vet. As a submerged aquatic plant it is rarely accessible to pets, but do not assume it is safe.
