It depends on which zoo they are different. When a bad zoo is bad, when a good zoo is good. Folding your opinion you should get rid of anthropocentrism and anthropomorphism of animals. For us, people, the cells are “prison”, this is “non-freedom” and this is a priori bad. But animals are not people. In nature, in general, there is no "freedom", it is a myth like the "pious savage" Rousseau. Under natural conditions, as a rule, the habitat of animals is limited to the territory sandwiched between the same territories of neighboring individuals, and when they try to cross their border, they will be attacked and possibly killed. For some small animals, their aviary in the zoo is many times more free and spacious than where they live in "nature". In many cases, the walls of the cage and the enclosures of the enclosures, they do not keep animals there, no, they protect animals from us here.

I think animals should not be in a zoo, but in their natural environment - nature. Because the zoo isolates animals from their original habitat.
