Why do bears in the northern hemisphere only hibernate in caves that open to the north?

Answer 1

Lies, lies and slander.

Answer 2

Can you prove that?  Got a scientific sources that backs up that statement?  Which bear specie are you talking about?  Which bears are in the southern hemisphere?  You know there aren't any caves in the Arctic.

There is no proof of your cave statement.  Not all bears hibernate.  Fact is few animals actually hibernate.  Polar bear hibernate in ice caves they make.  They can come out of them any direction they choose.
