* Lactose Intolerance: Guinea pigs, like many other animals, are lactose intolerant. This means they lack the enzyme lactase needed to digest lactose, the sugar in milk.
* Diarrhea and Stomach Upset: Undigested lactose ferments in the gut, leading to diarrhea, gas, bloating, and abdominal pain.
* Dehydration: Diarrhea can lead to dehydration, which can be life-threatening for small animals like guinea pigs.
* Other Health Problems: Long-term consumption of cow's milk can also lead to bone problems, kidney issues, and even death.
What should guinea pigs drink?
* Fresh water: This is the most important and only liquid guinea pigs need.
* Hay: Hay is a natural source of moisture for guinea pigs.
If you suspect your guinea pig has drunk cow's milk, contact your veterinarian immediately. They may recommend supportive care to help your guinea pig recover.
