Do you want to start a business to make some extra money? Maybe the only thing that stops you is money. There is one business that anyone can start. You don’t need any money. All that is necessary is patience(耐心). This is the business of pet sitting. 

In the US over 70% of all homes have pets, and in 2005 Americans spent over14 billion dollars on their pets. That is why pet sitters are needed. 

If you want to be a pet sitter, make sure that you have some knowledge of pets. Dogs and cats are quite easy to take care of. Birds are harder. And snakes and turtles may be special and could even be dangerous if you are not familiar with them. Pets need sleep and rest. They also need activities and exercise. Some even need medical care. But all pets need patience and love.
