Is Philodendron Gloriosum toxic to cats?

Yes — philodendron gloriosum is toxic to cats according to the ASPCA. Keep it well away from any cat that chews plants; reactions can be significant. The ASPCA lists Philodendron (Araceae) as toxic to cats, dogs, and horses; the species P. gloriosum is not listed individually, so this is based on the genus listing. The toxic principle is insoluble calcium oxalate crystals, which cause oral irritation, drooling, mouth and tongue swelling, vomiting, and difficulty swallowing if chewed.

The ASPCA lists Philodendron (Araceae) as toxic to cats, dogs, and horses; the species P. gloriosum is not listed individually, so this is based on the genus listing. The toxic principle is insoluble calcium oxalate crystals, which cause oral irritation, drooling, mouth and tongue swelling, vomiting, and difficulty swallowing if chewed. 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 philodendron gloriosum.

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: Philodendron Gloriosum is toxic to dogs as well. See the full philodendron gloriosum pet-safety guide for both species.
