All creature would want a freedom. Freedom of movement, speech and creativity. It is a common thing that living beings like us (humans) want. But what about the right to freedom of animals? in this case is often overlooked by us. We were talks about birds that often become human pets by having to live a limited lifestyle (confined).
Maybe we'll never want to think about what's in the animal's mind. What is certain, however, is that living in a cage and in a limited way is not what all living beings really want. To be able to imagine maybe we can try to stay in a cell of detention for a day. So all things experienced by all animals whose lives are limited by humans will soon be answered. Basically all living things have the same rights, but each has a different perspective.
