Can Guinea Pigs Drink Milk: A Guide to Safely Feeding Milk to Baby Cavies

No, guinea pigs cannot drink milk. These rodents are lactose intolerant and should not be given dairy products like milk. However, as mammals, baby guinea pigs must be nursed by their mothers. There are various substitutes, such as goat and soy milk, if a mother cavy’s milk is unavailable.

Health Risks of Drinking Milk for Guinea Pigs

Guinea pigs are sensitive to dairy, which means that milk is not a good option for their diet. However, milk can be a significant source of sugar for guinea pigs and cause health risks such as diabetes and obesity in the long term.

Lactose Intolerance

Guinea pigs are not able to digest lactose, the sugar in milk. This can lead to intestinal blockage and sickness in guinea pigs.

If your guinea pig does get sick from drinking milk, there are various remedies you can try. Some of these include giving them water mixed with a little lactose-free milk or vegetable juice, feeding them small pieces of fresh fruit instead of milk, administering probiotics through their feed or water bottles, or sponging their stomachs with warm water and baking soda several times a day.

Feeding them hay or other high-fiber foods instead of milk will help maintain their health and prevent problems from developing later. It’s essential to keep their diet healthy and free of dairy, so they don’t create health problems.

The Kind of Milk They Drink

Baby guinea pigs need a special kind of milk to drink – cow’s milk is not suitable for them. You can give them soy or almond milk as substitutes, but make sure to dilute it first. If your guinea pig isn’t eating well or seems unhappy, switching to goat’s milk might be better.

How Long They Drink Milk

Baby guinea pigs drink milk for about three to four weeks from birth. The amount will gradually decrease as the guinea pig becomes weaned off its mother’s milk and starts eating solid food.

It is important to note that the amount of milk guinea pigs drinks depends on their age, weight, and activity level. For example, guinea pigs stop drinking dairy entirely once they start feeding on solid food instead.


Bottle-feeding baby guinea pigs is a great way to reduce stress in the household and help them bond with their human caregivers. Guinea pig milk from bottles does not have to be watered down; it’s usually just as nutritious as water.

Several factors you should consider when bottle feeding your guinea pig include gradually introducing milk to their diet and decreasing the amount of water they drink over time.

Milk for Baby Guinea Pigs

Baby guinea pigs can drink milk from their nursing mothers or one uniquely formulated for them. If you’re bottle-feeding your guinea pig, they will need an amount dependent on their weight.

Cow Milk

Guinea pigs cannot drink cow milk even when diluted with water or fruit juices. Furthermore, guinea pigs are lactose intolerant and cannot digest milk properly. As a result, they may develop diarrhea and become overweight if given too much of it. Therefore, please provide fresh vegetables and fruits to fulfill their nutritional needs.

Goat Milk

Baby guinea pigs can drink goat’s milk, but it is not recommended as the high-fat content of this milk may cause health problems.

Giving them a mixture of water and goat’s milk is better to avoid problems while ensuring they get the essential nutrients they need. Guinea pigs are lactose intolerant and cannot digest milk properly, so feeding them goat milk may only worsen their condition.

Kitten Milk

Kitten milk is not a good substitute for guinea pig milk. If you decide to give your baby guinea pig some kitten milk (though this is not recommended), mix it with water first so they don’t get too thirsty!

Soy Milk

Guinea pigs can drink soy milk, but it’s not recommended. So it’s crucial to keep soy milk in an easily accessible place so your guinea pig can access it when they want it.

Guinea pigs should only drink small amounts at a time, and overindulging can lead to health problems later in life! Soybeans are a good source of protein for guinea pigs, and they’ll also benefit from soy milk.

Coconut Milk

Guinea pigs can drink coconut milk, but there are a few things to remember. First, please ensure no chunks in the coconut milk, so your guinea pig doesn’t choke on them. Coconut milk is high in fat and should only be given to healthy guinea pigs under the supervision of a vet.

Almond Milk

For guinea pigs, it’s essential to feed them a nut-free diet if you want to keep their teeth healthy. This means almond milk is a no-go, as it contains harmful bacteria that can cause tooth decay.

In addition to a nut-free diet, guinea pigs also need hay, fresh vegetables, and water to stay healthy.

Milk Chocolate

Guinea pigs are adorable creatures that can be fun to watch and play with. However, feeding them milk chocolate is not a good idea due to their inability to digest it. Guinea pigs are omnivores, which means they will eat other foods if given a chance.

So, if you provide them with milk chocolate, ensure it’s the unsweetened variety and sparingly. In addition to feeding your guinea pig a healthy diet, providing plenty of hay, fresh vegetables, and fruit is best for their overall health and happiness!

Oat Milk

Guinea pigs can drink oat milk, but it’s not recommended for pregnant or nursing mothers. Oat milk is high in nutrients and helps to regulate guinea pig food intake. Feed your guinea pig oat milk daily as part of their regular diet, and you’ll be good to go. It’s also easy to make – add water and oats to a blender or food processor and blend until smooth!
