Cats can eat applesauce, but only in very small amounts and occasionally. It must be all-natural applesauce without preservatives, added sugars, or harmful additives like cinnamon or other spices. Cats are obligate carnivores and do not require fruit in their diet; applesauce provides little nutritional benefit and may have risks due to sugar content, which can lead to obesity, tooth decay, and digestive upset. Additionally, apple seeds, stems, and leaves contain cyanide and are toxic to cats, so applesauce should be free of these parts. Overall, applesauce is not harmful in tiny amounts but not particularly good or necessary for cats either. A high-protein snack would be a better treat option than applesauce for cats.
