Is glasswort safe for cats and dogs?
Mildly. The ASPCA flags glasswort as mildly toxic to cats and dogs — a chewing pet gets oral irritation and drooling rather than a medical emergency, but it is still worth a high shelf. 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. Salicornia europaea is not listed on the ASPCA Toxic Plant database for cats or dogs, and the young shoots are widely eaten by humans. However, the extremely high sodium content can cause salt toxicity, vomiting, and diarrhoea in dogs and cats if consumed in any significant quantity; treat as mildly toxic and keep out of reach of pets.
| Pet | Toxic? | Per ASPCA |
|---|---|---|
| Cats | Yes (mild) | Mildly toxic to pets |
| Dogs | Yes (mild) | Mildly toxic to pets |
What happens if a pet eats glasswort?
