Is Cranberry 'Stevens' toxic to cats?

Mildly. The ASPCA lists cranberry 'stevens' 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. Vaccinium macrocarpon and its cultivars are not individually listed in the ASPCA Toxic/Non-Toxic Plants database, so the pet status is unconfirmed; cranberry fruit is an established human food with no systemic toxin, but ingesting plant material may cause mild gastrointestinal upset in cats and dogs. Treat with caution and verify with a vet rather than labelling it pet-safe.

Treat with caution and verify with a vet rather than labelling it pet-safe. 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 cranberry 'stevens'.

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 in the US, or Animal PoisonLine on 01202 509 000 in the UK 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: Cranberry 'Stevens' is mildly toxic to dogs as well. See the full cranberry 'stevens' pet-safety guide for both species.
