Is California Fan Palm toxic to cats?

Mildly. The ASPCA lists california fan palm 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. Washingtonia filifera is not individually listed on the ASPCA toxic-or-non-toxic database, so a definitive pet-safe label cannot be given; treat with caution and verify with a vet. It is not a known-toxic genus, but ingested fronds or seeds may cause mild GI upset, and the spined petioles can injure pets that chew or brush against them.

Washingtonia filifera is not individually listed on the ASPCA toxic-or-non-toxic database, so a definitive pet-safe label cannot be given; treat with caution and verify with a vet. It is not a known-toxic genus, but ingested fronds or seeds may cause mild GI upset, and the spined petioles can injure pets that chew or brush against 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 california fan palm.

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.
