Question:

Why is it that wild animals can drink water that’s unsafe for humans?

Answer:

There are long, complex answers to your question, but here are two responses I think are important. First, wild animals do get sick, and sometimes they get sick from the water they drink. They often have diarrhea, and sometimes they die from their illnesses. But, yes, sometimes they can drink water that we cannot tolerate because they have developed immunities that we have not.
