Is blue moor grass safe for cats and dogs?
Not entirely — blue moor grass 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. Sesleria caerulea is not individually listed on the ASPCA Toxic or Non-Toxic Plant database, and the genus Sesleria carries no specific ASPCA entry, so pet-safe status cannot be confirmed. Treat with caution and verify with a vet. The realistic risk is mechanical, blades and seed awns can irritate the mouth or gut if eaten, rather than documented chemical toxicity.
| Pet | Toxic? | Per ASPCA |
|---|---|---|
| Cats | Yes (mild) | Mildly toxic to pets |
