A few years ago there was a zoo where they brought up two pola bear cubs. I forget if they were brother or sister or brothers. They were cute. They got to an age where they just became dangerous. They had some small pvc containers like small beer kegs. They got pissed off and started swatting them around in a furor because for some reason they got mad.
They are beautiful animals but they are predators. I think zoos suck and they should not lock animals up in confined areas. A great place is woman in TN who has a private preserve for old elephants. I think mainly Asian elephants. They are amazing animals but need lots of room to roam.
I saw that,one of them got p*ssed and bit a bottle with formula or some liquid and he burst the damn thing.Fluid flew everywhere and he was still relatively small.I`d say about the size of a larger medium breed dog.Well think about it,if a dog can tear you up,imagine a wild animal like a bear.
