An aphorism that I strenuously advocate is that animals should be free. That is why I am averse to zoos and even caged birds. Like humans, all animals have certain rights and one of those is freedom. Amongst others is that they must be able to feel real grass under their feet and not to be confined in the animal equivalent of “solitary confinement.”
