We know that hamsters regularly drink water, but for this post we are going to look at the question ‘can hamsters drink milk?’
Milk is a pale liquid produced by the mammary glands of mammals. It is the primary source of nutrition for infant mammals before they are able to digest other types of food.
The composition of milk differs widely among species. Factors such as the type of protein; the proportion of protein, fat, and sugar; the levels of various vitamins and minerals; and the size of the butterfat globules, and the strength of the curd are among those that may vary.
Human milk contains, on average, 1.1% protein, 4.2% fat, 7.0% lactose (a sugar), and supplies 72 kcal of energy per 100 grams.
Cow’s milk contains, on average, 3.4% protein, 3.6% fat, and 4.6% lactose, 0.7% minerals and supplies 66 kcal of energy per 100 grams.
Donkey and horse milk have the lowest fat content, while the milk of seals and whales may contain more than 50% fat (source)
So can hamsters drink milk?
They can’t really drink it.
All kinds of milk are not really good for them and may make them sick.
Some owners give them fat free milk but they are better fed water than milk.
