Nutritional breakdown for cats
While some healthy cats may tolerate small tastes of soy milk, 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 soy milk entirely in favor of safer, nutrient balanced treats.
