Nutritional breakdown for hamsters
While some healthy hamsters may tolerate small tastes of peanut butter, there is a higher risk of gastrointestinal upset or longer-term issues if it is given frequently or in large amounts. Because cats and dogs have very different metabolism from humans, the same healthy fats or plant compounds we enjoy can stress their digestive system or organs. Many veterinary nutritionists recommend skipping peanut butter entirely in favor of safer, nutrient balanced treats.
