Is Cryptocoryne undulata toxic to cats?

Mildly. The ASPCA lists cryptocoryne undulata 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. Not individually listed by the ASPCA, so the status is undetermined; treat with caution and verify with a vet. Cryptocoryne belongs to the Araceae family, whose members contain insoluble calcium oxalate crystals; a pet chewing emersed leaves may show oral irritation, drooling or vomiting. Never label pet-safe without ASPCA grounding.

Not individually listed by the ASPCA, so the status is undetermined; treat with caution and verify with a vet. Cryptocoryne belongs to the Araceae family, whose members contain insoluble calcium oxalate crystals; a pet chewing emersed leaves may show oral irritation, drooling or vomiting. Never label pet-safe without ASPCA grounding. 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 cryptocoryne undulata.

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: Cryptocoryne undulata is mildly toxic to dogs as well. See the full cryptocoryne undulata pet-safety guide for both species.
