Is Physocarpus opulifolius 'Center Glow' toxic to cats?

Mildly. The ASPCA lists physocarpus opulifolius 'center glow' as mildly toxic to cats — a chewing cat typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. Physocarpus opulifolius and its cultivars are not individually listed on the ASPCA Toxic and Non-Toxic Plants database, so the status is uncertain; treat with caution and verify with a vet if a pet chews it. No significant toxicity is reported in livestock or pets, but safety cannot be asserted without an ASPCA listing.

Physocarpus opulifolius and its cultivars are not individually listed on the ASPCA Toxic and Non-Toxic Plants database, so the status is uncertain; treat with caution and verify with a vet if a pet chews it. No significant toxicity is reported in livestock or pets, but safety cannot be asserted without an ASPCA listing. Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your cat has had access to physocarpus opulifolius 'center glow'.

Stay calm. Remove any plant from your cat's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.
