Is Wisteria floribunda toxic to cats?

Yes — wisteria floribunda is toxic to cats according to the ASPCA. Keep it well away from any cat that chews plants; reactions can be significant. The ASPCA lists Wisteria as toxic to cats, dogs and horses. The toxic principles are lectin and wisterin glycoside, concentrated in the seeds and pods. Ingestion causes vomiting (occasionally with blood), diarrhoea and depression, and even a few seeds can cause significant illness. Remove and dispose of seed pods where pets or children could reach them.

Remove and dispose of seed pods where pets or children could reach them. 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 wisteria floribunda.

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: Wisteria floribunda is toxic to dogs as well. See the full wisteria floribunda pet-safety guide for both species.
