Is Fallopia baldschuanica toxic to cats?

Mildly. The ASPCA lists fallopia baldschuanica 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. Fallopia baldschuanica is not individually listed in the ASPCA Toxic and Non-Toxic Plants database, so its status is unverified; treat with caution and verify with a vet before assuming it is safe around pets. As a knotweed-family climber it is not a known severe toxin, but absence from the ASPCA list means pet-safety cannot be asserted.

Fallopia baldschuanica is not individually listed in the ASPCA Toxic and Non-Toxic Plants database, so its status is unverified; treat with caution and verify with a vet before assuming it is safe around pets. As a knotweed-family climber it is not a known severe toxin, but absence from the ASPCA list means pet-safety cannot be asserted. 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 fallopia baldschuanica.

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: Fallopia baldschuanica is mildly toxic to dogs as well. See the full fallopia baldschuanica pet-safety guide for both species.
