Is Nepenthes sibuyanensis toxic to cats?

Mildly. The ASPCA lists nepenthes sibuyanensis 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. Nepenthes is not individually listed in the ASPCA Toxic and Non-Toxic Plants database; only the unrelated California pitcher plant (Darlingtonia californica) is listed there, as non-toxic. Without ASPCA verification for Nepenthes, treat it with caution: chewing foliage or acidic pitcher fluid may cause mild oral or digestive irritation. Verify with a vet before assuming pet-safe.

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 nepenthes sibuyanensis.

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: Nepenthes sibuyanensis is mildly toxic to dogs as well. See the full nepenthes sibuyanensis pet-safety guide for both species.
