Recently, a law was enacted in Saudi Arabia that bans men from owning cats or dogs because they might use them to pick up women. However, the USA has plenty of silly animal laws as well.
California
Various places in California have enacted a plethora of ludicrous laws at one time or another. These laws include prohibiting:
Giving away kittens or puppies.
Driving a very large sheep herd through Hollywood.
Mountain lions mating within 1,500 feet of a school, tavern, or religious establishment.
Cats and dogs engaging in sexual activities without permits.
In San Francisco, you may walk your pet lion down Market Street provided he’s on a leash, but if you and your lion wish to engage in acts of mass destruction, you should be aware that the fine for detonating a nuclear device is $500.
Colorado
In Sterling, cats that sneak out of the house must wear tail lights.
Florida
Florida appears to have had serious issues with aggression in the past. In Destin, you can be fined $100 if your cat is aggressive, and it is illegal to set off torpedoes, rockets, and other explosives in city parks, while Daytona has a law against beating or molesting trash cans.
Illinois
Corrupting domestic animals was once a large problem in Illinois, judging by the laws that have been enacted in various places around the state. There are prohibitions against:
Giving lighted cigars to cats, dogs, and other pets.
