Sesame oil is not considered toxic to cats. Still, it is best to avoid feeding it to cats. Cats have specific nutritional needs, and their primary source of nutrition should come from a well-balanced cat food. Introducing oils such as sesame oil into their diet can lead to digestive problems and other potential complications. If you are going to introduce any new food to your feline it is recommended to consult your veterinarian to ensure it does not bring any potential harm.
