Is Dyckia leptostachya toxic to cats?

Mildly. The ASPCA lists dyckia leptostachya 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. Dyckia is not individually listed by the ASPCA and has no genus-level ASPCA classification, so its toxicity is treated as uncertain; verify with a vet before assuming it is pet-safe. The bigger hazard is mechanical: its hook-spined leaf margins can badly cut a pet's mouth, paws or a handler's skin.

Dyckia is not individually listed by the ASPCA and has no genus-level ASPCA classification, so its toxicity is treated as uncertain; verify with a vet before assuming it is pet-safe. The bigger hazard is mechanical: its hook-spined leaf margins can badly cut a pet's mouth, paws or a handler's skin. 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 dyckia leptostachya.

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: Dyckia leptostachya is mildly toxic to dogs as well. See the full dyckia leptostachya pet-safety guide for both species.
