“bears are usually not carnivorous.”
Ever been near bears when they are hungry? How about mountain lions that can snag a child faster than any wolf and with much more stealth? We don’t put kids in cages for either of them. We’ve also got Bobcats and Lynx. Wolves have also been reintroduced into Colorado. We still don’t use cages.
That is your decision to make.
These people made theirs and do not deserve criticism for it.
Most people want to keep their kids safe.
