Sesame seeds are not toxic to cats, but they can pose a choking hazard, especially for kittens or older cats.
Additionally, they are high in fat which can lead to digestive upset or contribute to obesity if consumed in large quantities.
Suggestions
If you want to give your cat sesame seeds, do so sparingly and ensure they are properly ground or processed to minimize choking risks.
Monitor your cat for any signs of digestive upset after consumption.
Note: even if labeled as safe, any food can potentially cause allergies. When introducing a new food, please feed a small amount and observe your cat for any allergic reactions.
