There are many hobbies.For example,some people play on the instrument or collect something.And the hobby of some people is keeping pets.I think that keeping is very good idea. In towns and cities are generally kept dogs,cats,hamsters,and in the country usually kept cows,sheep,horses,big dogs and others.Sometimes people keep unusual pets,for example monkeys.The most unusal pet i have heard of was line.If you want a pet you must know what problems do people face if they keep pets.They are diffrent.For example,you must go with it for a walk,gave it food and water,go with it to animal doctor and others.I never have pet?but i want a puppy.
