Is kale safe for cats and dogs?
Use caution. Kale is on the mildly-toxic side of the ASPCA list. Most ingestions are short-lived but unpleasant for the pet; the cost-free fix is a placement they can't reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. ASPCA lists Brassica species as toxic to cats, dogs, and especially horses in quantity. Small amounts of cooked kale are widely fed to dogs without issue; large raw amounts can cause GI upset and goitrogen issues over time.
| Pet | Toxic? | Per ASPCA |
|---|---|---|
| Cats | Yes (mild) | Mildly toxic to pets |
| Dogs | Yes (mild) | Mildly toxic to pets |
