Is Sintenis's Rock Rose toxic to cats?

Mildly. The ASPCA lists sintenis'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 sintenisii is not recorded in the ASPCA Toxic and Non-Toxic Plant database and no toxic principles have been identified for this species in veterinary literature. The precautionary classification of mildly-toxic is applied because the species is not formally confirmed as non-toxic; ingestion may cause mild gastrointestinal upset in pets.

Cistus sintenisii is not recorded in the ASPCA Toxic and Non-Toxic Plant database and no toxic principles have been identified for this species in veterinary literature. The precautionary classification of mildly-toxic is applied because the species is not formally confirmed as non-toxic; ingestion may cause mild gastrointestinal upset in pets. 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 sintenis'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: Sintenis's Rock Rose is mildly toxic to dogs as well. See the full sintenis's rock rose pet-safety guide for both species.
