Is purple fountain grass safe for cats and dogs?
Not entirely — purple fountain 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. Pennisetum setaceum is not individually listed in the ASPCA toxic plant database, and the sterile cultivar 'Rubrum' is widely regarded as non-toxic; because there is no direct ASPCA listing, treat its safety as uncertain and confirm with a vet. The clearer hazard is mechanical — bristly, sharp-awned plumes and blades can irritate or lodge in pets, and eating grass can cause mild GI upset.
| Pet | Toxic? | Per ASPCA |
