The main differences between cats drinking cow's milk and goat's milk are as follows:
1. Cow's milk has a high lactose content, and most cats are lactose intolerant, unable to effectively digest lactose, which may lead to problems such as diarrhea. In contrast, goat's milk has a lower lactose content, making it less likely for cats to be intolerant.
2: The protein structure of goat milk is different from that of cow milk, and is closer to the milk of female cats. In addition, the fat globules in goat milk are smaller and the content of unsaturated fatty acids is higher, making it easier for cats to digest and absorb.

3. Goat milk is superior to cow milk in terms of calcium content, vitamins, and trace elements, and can better meet the nutritional needs of cats.
In conclusion, goat milk is more suitable for cats, especially cats with lactose intolerance.
