Cats can eat small amounts of sunflower seeds, but it's not recommended to feed them frequently or in large quantities. Sunflower seeds contain fat, trace elements, and minerals, which can supplement a cat's diet with small amounts of protein and minerals.

However, since commercially available sunflower seeds are usually roasted with seasonings and have a high fat content, feeding cats too many sunflower seeds can lead to obesity and an inability to metabolize the seasonings.
