Is Osbeck's Rock Rose toxic to cats?

Mildly. The ASPCA lists osbeck's rock rose 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. Cistus osbeckiifolius is not listed on the ASPCA Toxic and Non-Toxic Plants database and no specific toxic compound has been confirmed in veterinary literature for this species. As a precaution, given the absence of explicit non-toxic confirmation, it is classified as mildly toxic; seek veterinary advice if pets ingest significant quantities.

As a precaution, given the absence of explicit non-toxic confirmation, it is classified as mildly toxic; seek veterinary advice if pets ingest significant quantities. 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 osbeck's rock rose.

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: Osbeck's Rock Rose is mildly toxic to dogs as well. See the full osbeck's rock rose pet-safety guide for both species.
