Feeding pets human food can be dangerous for several reasons. Some human foods can be toxic to pets, such as chocolate, grapes, onions, garlic, and xylitol (an artificial sweetener). Additionally, human food can be too high in fat, salt, or sugar, which can lead to health issues like obesity, diabetes, or pancreatitis in pets. It's important to stick to a balanced and appropriate diet specifically formulated for your pet's needs to ensure their health and well-being.
