In 2007, riders on the 331 bus in the United Kingdom began to notice a fellow passenger -- a white cat that would board the bus several days a week at the Churchill Road stop and exit near a fish-and-chips shop about 400 meters (.25 miles) down the road. Passengers affectionately nicknamed the kitty Macavity, after the mysterious cat featured in the T.S. Eliot book of poems "Old Possum's Book of Practical Cats," once they realized the cat was riding the bus without its owner [source: The Daily Mail].
Could you blame this resourceful feline? Public transportation is such a convenient, cheap and eco-friendly way to travel -- and you can even nap while you do it! Public transportation is a great way for people to get around, especially in major cities where roads are clogged and parking is scarce. There's only one question, though: Can your dog or cat (legally) ride with you?
The good news is that certain buses, trains, trolleys and light rails allow pets. However, don't get your best friend leashed up yet -- a number of restrictions apply, and you're out of luck if you're traveling Greyhound or Amtrak, as neither allows pets on its buses and trains.
There's one exception to that rule: If you have a service animal, the Americans with Disabilities Act (ADA) allows your animal to accompany you to any public place, from restaurants and hotels to (you guessed it) buses and trains. However, service animals are workers, not pets, and many more restrictions apply to them. Generally, you'll have more luck if your pet is small enough to fit in a large bag or small carrier. If you have a large dog, some modes of public transportation in certain cities will allow you to take it with you, but those transportation companies are much fewer than those that allow small pets. Recently, restrictions in some parts of the United States against transporting pets were amended to allow some pets to use public transportation and receive care during emergencies [source: Texas A&M University]. After Hurricane Katrina, the U.S. government realized that some people refused mandatory evacuation on public buses because they could not take their animals with them.
