Can Cats Eat Yogurt? Complete Safety & Nutrition Guide
Quick Answer: Cats can eat plain, unsweetened yogurt in very small amounts, but most adult cats are lactose intolerant. According to the ASPCA (American Society for the Prevention of Cruelty to Animals) and Cornell University College of Veterinary Medicine, plain yogurt can provide probiotics, but it must be free of added sugar, artificial sweeteners (especially xylitol), and flavors. This comprehensive guide is based on veterinary nutrition research and probiotic studies.Is Yogurt Safe for Cats?
The ASPCA (American Society for the Prevention of Cruelty to Animals) and Cornell University College of Veterinary Medicine confirm that plain, unsweetened yogurt is generally safe for cats when fed in very small amounts. However, most adult cats are lactose intolerant, and yogurt must be free of toxic ingredients like xylitol.
Important considerations:- Most cats are lactose intolerant - Adult cats lack sufficient lactase enzyme
- Xylitol is extremely toxic - Never feed yogurt containing xylitol
- High fat content - Can contribute to obesity and pancreatitis
- Not nutritionally necessary - Cats don't need dairy
