Spend 24 hours locked in a very small room—no privacy, nothing whatsoever to do to pass the time—and you will have a taste of what animals endure at roadside displays. Whether they’re called safari parks, petting zoos, or game farms, they are at the bottom of the heap in the zoo world.

Captivity-induced mental illness is rampant among confined animals. Some rage against their imprisonment and frantically claw at the bars. Others, having succumbed to relentless boredom, show little interest in anything.

The preference for cute babies—particularly for photo ops—leads to a chronic surplus of adult animals with nowhere safe to go. Many animals end up being sold at auctions—used for canned hunts or even sold for exotic meats.

There are “less than 90” U.S. Department of Agriculture inspectors to oversee 10,000 breeders, dealers, and exhibitors. Inspections occur once a year, sometimes even less frequently, and the laws are pitifully inadequate, mandating only minimal standards of care. It is perfectly legal to keep a chimpanzee isolated in a small cage for his or her entire life or provide a 10-foot, 600-pound tiger with only a fraction of the living space given to the average 10-pound housecat.

The number of excess big cats in the United States is simply staggering. More breeding does nothing to help wild populations; it only adds to the number of surplus animals. No captive breeding of endangered big carnivores (such as tigers, lions, or leopards) has resulted in the release of those animals back into their natural home.

Encouraged by roadside and traveling zoos, countless people every year succumb to the temptation to purchase exotic animals like hedgehogs, macaws, lizards—even tigers, bears, and monkeys—as "pets." Life in captivity is often a death sentence for these animals, who may suffer from malnutrition, an unsuitable environment, loneliness, and the stress of confinement.

Animals used in traveling menageries are often subjected to severe abuse and deprivation in order to provide "entertainment" at county fairs, shopping malls, and theme parks. Confined to tiny transport cages, animals endure constant stress. They often suffer from temperature extremes, irregular feeding and watering, and lack of exercise. Incidences of animals attacking spectators, especially children, are frequent.

Captivity can be hell for animals meant to roam free. Kept in small, barren cages, forced to sleep on concrete slabs behind iron bars, animals often suffer from malnutrition, loneliness, loss of independence, and even lack of veterinary care. Attracting customers is the first consideration, and the animals' welfare is often the last.

No genuine sanctuary would make a bad situation worse by breeding, buying, or selling animals. Roadside zoos operating under the sanctuary banner take advantage of the public while mistreating the animals in their care.

There is no legitimate educational value associated with these substandard exhibits. True respect for wildlife is stimulated by learning about them in their natural habitat, not by dragging them around in small cages to neighborhood malls and fairgrounds, which perpetuates the notion that dangerous animals can be made into "pets."

Wildlife pimps reduce animals—even endangered species—to oddities, stage props, trophies, prisoners, and pawns.
