Is Thunbergia grandiflora toxic to cats?

Mildly. The ASPCA lists thunbergia grandiflora 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. Not individually listed by the ASPCA, so its pet status is unconfirmed; treat with caution and verify with a vet rather than assuming it is safe. Ingestion of plant material may cause mild stomach upset and vomiting in cats and dogs, so keep pets from chewing the leaves and flowers.

Not individually listed by the ASPCA, so its pet status is unconfirmed; treat with caution and verify with a vet rather than assuming it is safe. Ingestion of plant material may cause mild stomach upset and vomiting in cats and dogs, so keep pets from chewing the leaves and flowers. 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 thunbergia grandiflora.

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.

The ASPCA classification Growli uses applies to both cats and dogs: Thunbergia grandiflora is mildly toxic to dogs as well. See the full thunbergia grandiflora pet-safety guide for both species.
