Is White Konjac toxic to cats?

Yes — white konjac is toxic to cats according to the ASPCA. Keep it well away from any cat that chews plants; reactions can be significant. All Amorphophallus species contain insoluble calcium oxalate raphides throughout their tissues. Raw corms cause severe oral irritation, burning, and swelling in people, dogs, and cats. The corm is rendered edible only after thorough cooking or drying, which breaks down the oxalate crystals. Keep raw plant material away from pets and children.

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 white konjac.

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: White Konjac is toxic to dogs as well. See the full white konjac pet-safety guide for both species.
