Americans love pets. In America, there are more families with pets    1    those with children. It is common    2     U.S. homes have some sort of pets, such as monkeys, snakes and even wolves. But Americans’ all-time favorites are cats and dogs, because dogs can offer protection from thieves and unwelcome visitors and cats can help get rid    3     the home unwanted pests. Beneath keeping pets, there lies a basic American belief: Pets have a right to be treated well. In Houston, Texas, dogs can have their dinner    4     (deliver) to their homes, just like pizza.
