Many people like animals, and often keep one or more of dogs and cats as pets(宠物). If you keep a dog or a cat
as a pet, you must look after it.
A grown-up(成年的)dog needs two meals a day-not more. It can eat meat, fish, rice and some other things. Dogs
like bones(骨头), but you can't give 
them chicken bones. Remember to give them a lot of clean water.
A dog should have a clean, dry box for sleeping(睡觉) in. Washing it once a week is good for its health. If it is ill,
take it to a vet(兽医). A healthy dog will bring you more pleasure.
Be careful when you choose(挑选)a cat. A cat has two meals a day with some meat or fish. It drinks a little milk
every day. Sometimes you can give them vegetables to eat. Don't forget that they need clean water to drink.
Take good care of your pets. They will be your good friends. Maybe they can give you some help when you are
in need.
