Plain air-popped kernels (no butter, salt or caramel) are okay in small amounts. Unpopped kernels can damage teeth.
Short answer
Yes, plain air‑popped popcorn can be offered to a cat in very small amounts. Make sure it’s completely unbuttered, unsalted and free of caramel or other flavorings. Watch for any hard kernels that could hurt teeth or cause choking, and monitor for vomiting or stomach upset. If any of those signs appear, call your vet.
