Is Sorbus 'Joseph Rock' toxic to cats?

Mildly. The ASPCA lists sorbus 'joseph rock' 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. Sorbus is not individually listed by the ASPCA, so its pet status is unconfirmed; treat with caution and verify with a vet. The berry seeds contain cyanogenic glycosides, so a pet chewing a large quantity of berries could experience mild gastrointestinal upset, though in practice signs are usually limited to short-lived vomiting or diarrhoea.

The berry seeds contain cyanogenic glycosides, so a pet chewing a large quantity of berries could experience mild gastrointestinal upset, though in practice signs are usually limited to short-lived vomiting or diarrhoea. 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 sorbus 'joseph rock'.

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.
