Yes, plain water chestnuts are non-toxic in small amounts.
Why it’s fine
Despite the name, water chestnuts are aquatic vegetables, not nuts, and they are non-toxic with a crunchy texture some cats enjoy. They are starchy rather than nutritious for a carnivore, and canned versions sit in salty water that needs rinsing.
How to serve it safely
Offer a small piece of fresh or well-rinsed canned water chestnut occasionally.
When to call the vet
Call your vet only if digestive upset persists.
Common questions
Are they safe for cats with nut allergies?
Yes — they are vegetables with no botanical link to tree nuts, so a nut-allergic cat is not at risk from them.
