Is gyoku-ryu mondo grass safe for cats and dogs?
Mildly. The ASPCA flags gyoku-ryu mondo grass 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. Ophiopogon japonicus is not individually listed by the ASPCA on either its toxic or non-toxic plant lists; it is widely reported as non-toxic but lacks an explicit ASPCA listing, so treat with caution and verify with a vet. No specific toxic principle is documented; ingestion of foliage or any berries may cause mild vomiting or gastrointestinal upset in cats and dogs.
| Pet | Toxic? | Per ASPCA |
