Here's why:
* Lactose Intolerance: Guinea pigs, like many other mammals, are lactose intolerant. This means they lack the enzyme lactase, which is needed to break down lactose (the sugar in milk). Consuming milk can cause digestive problems like diarrhea, gas, and bloating.
* Nutritional Imbalance: Milk is not a complete food for guinea pigs. It lacks essential vitamins, minerals, and fiber that they need for a healthy diet.
* Calcium Issues: While milk does have calcium, it can also cause calcium deposits in guinea pigs, leading to urinary tract issues.
What should you feed your guinea pig instead?
Guinea pigs are herbivores and need a diet consisting of:
* Hay: Timothy hay should make up the majority of their diet.
* Pellets: A small amount of high-quality guinea pig pellets should be given daily.
* Fresh Vegetables: A variety of fresh vegetables should be offered daily.
* Fruit: A small amount of fruit can be given occasionally as a treat.
If you're unsure about any aspect of your guinea pig's diet, it's best to consult with a veterinarian.
