Is Amelanchier canadensis toxic to cats?

Mildly. The ASPCA lists amelanchier canadensis 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. Not individually listed by the ASPCA, so its status is uncertain; treat with caution and verify with a vet. The ripe berries are edible and widely eaten, but the leaves, stems, seeds and unripe fruit contain cyanogenic glycosides (as in many Rosaceae) that can release cyanide in quantity, causing GI upset or worse. Do not assume pet-safe.

Do not assume 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 amelanchier canadensis.

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: Amelanchier canadensis is mildly toxic to dogs as well. See the full amelanchier canadensis pet-safety guide for both species.
