Is Witch Hazel toxic to cats?

Mildly. The ASPCA lists witch hazel 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. Hamamelis is not individually listed on the ASPCA toxic or non-toxic plant database, so its status is not confirmed by that authority; treat with caution and verify with a vet before assuming it is safe. The astringent tannins concentrated in commercial witch hazel extracts can cause stomach upset if ingested, which supports keeping pets from chewing the plant.

The astringent tannins concentrated in commercial witch hazel extracts can cause stomach upset if ingested, which supports keeping pets from chewing the plant. 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 witch hazel.

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: Witch Hazel is mildly toxic to dogs as well. See the full witch hazel pet-safety guide for both species.
