What this means for your cat
Cats are not poisoned by honey locust — ASPCA classifies Gleditsia triacanthos as non-toxic to cats. Don't confuse this with black locust (Robinia pseudoacacia), which is toxic; the honey locust's leaves, pods, and seeds carry no toxic principle, so an outdoor cat chewing leaves or batting at a fallen pod is not at risk of poisoning.

Questions about Honey Locust
Is honey locust toxic to cats?
Honey locust (Gleditsia triacanthos) is considered non-toxic to cats. It is classified as generally safe, meaning exposure or small ingestions are not expected to cause poisoning.
What happens if my cat eats honey locust leaves or seed pods?
No toxic effects are expected, but the fibrous plant material may cause mild vomiting or gastrointestinal upset if eaten in large quantities. Small nibbles are unlikely to cause any symptoms at all.
What should I do if my cat ate a lot of honey locust plant material?
Non-toxic does not mean harmless in large amounts — significant ingestion of fibrous material can cause GI upset. Monitor your cat for vomiting or signs of distress, and contact your veterinarian if symptoms develop or persist.
Does any part of the honey locust tree pose a physical hazard to cats?
Honey locusts have long, sharp thorns on their trunks and branches that could injure a curious cat. The plant itself is not chemically toxic, but physical contact with thorns is worth keeping in mind if the tree is in your yard.
