The thing is, we try to be nice to the animals. We try to let them live in our civilization so they have the chance to evolve with us but time after time they let us down and we have to round them up and put them in the zoo again.
This is what every parent should teach their children, when you decide to run the streets with a pack of animals and rob people and do criminal things you are just revealing to the humans that you are not one of them. You are showing them that you are one of the sub-human animals and when the humans see that, they will hunt you down and catch you and they will put you in your cage in the zoo. Once you are there you will see the zoo keepers (guards) don’t care what all the other animals do to you, they are just there to stop you all from getting out. The other animals will prey on you and abuse you just like you would expect animals to do and the humans will just look the other way because they don’t want to be bothered with what animals do to each other.
