Is Küster's Ceratozamia toxic to cats?

Yes — küster's ceratozamia is toxic to cats according to the ASPCA. Keep it well away from any cat that chews plants; reactions can be significant. Ceratozamia kuesteriana contains cycasin and BMAA neurotoxin throughout all tissues — leaves, roots, and seeds — consistent with all Zamiaceae family cycads. Ingestion causes vomiting, liver failure, neurological damage, and can be fatal to dogs and cats. ASPCA lists cycads as severely toxic. Even small amounts of seed or leaf material are dangerous to pets.

Ingestion causes vomiting, liver failure, neurological damage, and can be fatal to dogs and cats. ASPCA lists cycads as severely toxic. Even small amounts of seed or leaf material are dangerous to pets. 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 küster's ceratozamia.

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.
