Is Rose Apple toxic to cats?

Mildly. The ASPCA lists rose apple 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. Syzygium jambos is not individually listed by the ASPCA toxic/non-toxic plant database, so its pet status is unconfirmed; treat with caution and verify with a vet. The ripe fruit flesh is a long-established human food, but seeds and leaves of Syzygium species can contain trace cyanogenic and astringent compounds, so prevent pets from chewing seeds, leaves or bark.

The ripe fruit flesh is a long-established human food, but seeds and leaves of Syzygium species can contain trace cyanogenic and astringent compounds, so prevent pets from chewing seeds, leaves or bark. 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 rose apple.

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: Rose Apple is mildly toxic to dogs as well. See the full rose apple pet-safety guide for both species.
