Ask the Vet: 我給我的貓喝牛奶是安全的嗎?Is it safe for my cat to drink cow’s milk? 

Q&A with Dr Pauline Taylor, BVM&S MACVSc

從營養學的角度來說,貓不會從牛奶中獲得甚麼營養,奶對牠們來說只是一種特別高卡路里的零食。加上,牛奶中有很高的乳糖(糖份)和駱蛋白(蛋白質),高於貓能接受的分量。貓在斷奶後沒有那麼高的能力去分解牛奶中的糖份和蛋白質,牠們的腸道裏沒有一種叫乳糖酵素的酵素,因此當牠們喝牛奶後,攝入的糖份有機會引致腹瀉、脹氣和放屁。所以我並不建議你喂牛奶給你的貓

DR. PAULINE SAYS: Nutritionally cats do not get anything special from cow’s milk. Milk is really just a high calorie treat for them. In addition cow’s milk is loaded with more lactose [sugar] and casein [ protein] than most cats can handle. Cats’ bodies after weaning do not have the same ability to break up the sugars & proteins in milk, they do not have an enzyme called lactase in their gut, & as a result the ingested milk sugars can cause diarrhea, bloating and farting in cats drinking cow’s milk. I really don’t recommend you feed your cats cow’s milk.
