Dog leashes (chains) and dog crates (cages) as well as fenced in yards are used for the same purpose as a crib or a playpen for a child, to properly and safely contain a living creature. The “creatures” that you refer to are NOT “from” the wild. These animals were born in captivity and many if not most are fully domesticated since they are trained, bonded, and completely desensitized to humans. The definition of a wild animal is “living in a state of nature, not tamed or domesticated”. By definition, since elephants and big cats are born in this country, especially those in the circus, most zoos, and those in private ownership, they are not wild animals. These are facts, not emotion. There IS a difference between animal welfare and animal rights. RAW represents animal welfare and is extremely concerned and involved in the promotion of welfare regarding proper care and the responsibility of keeping animals in our lives. If your definition of animal welfare standards are only those that are kept in an air conditioned home and sleeping in bed with their owners, sadly many pet owners would be considered cruel by your standards. Horses have halters, leads, bridles and reins to control them, dogs have collars and leashes, all animals have some sort of restraining method to “keep or control” them. Whether an animal is kept in an aquarium/bird cage/dog crate type of “cage”, or in a home, barn, garage, (larger cage), is kept in a fenced yard or paddock (larger cage), this is simply a matter of semantics since they all accomplish the same thing: containment. Mental and physical stimulation is far more important than the type of “cage” that the animal is kept in.
