Cats can eat sesame seeds. Sesame seeds are rich in vitamins, such as B vitamins and vitamin E, as well as protein. These nutrients can promote gastrointestinal motility and provide cats with ample nutrition. The lecithin in sesame seeds can also help improve a cat's coat. However, it's important to feed them in moderation. Overfeeding can cause vomiting, diarrhea, and obesity in cats. 
Do cats need to hibernate?
Cats do not hibernate. Felines evolved thicker fur and are warm-blooded animals, able to regulate their body temperature. They continue hunting and eating throughout the winter. However, it's important to keep your cat warm in winter, otherwise they are prone to catching colds.
