Is stromanthe triostar safe for cats and dogs?
Use caution. Stromanthe Triostar 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. Stromanthe thalia (Triostar) is a prayer plant (family Marantaceae). It is not individually listed in the ASPCA database, and the ASPCA 'Prayer Plant' entry is filed under the related Calathea (Goeppertia), a different genus, so Stromanthe is not ASPCA-confirmed. It has no known toxic compounds and is generally kept safely around pets, but treat it as mildly toxic and check with your vet to be sure.
| Pet | Toxic? | Per ASPCA |
|---|---|---|
| Cats | Yes (mild) | Mildly toxic to pets |
| Dogs | Yes (mild) | Mildly toxic to pets |
