    Guinea Pigs (荷兰猪) are friendly animals that enjoy being held and seldom bite. They come from South

 America and can live as long as seven or eight years.

     Housing

     Your Guinea Pigs can be kept indoors all year round. They do not like sudden loud noises, so it's best 

 to put their cages in a quiet place. A wooden cage is good, although a metal cage can also be used if it has

 a plastic floor.

     Feeding

     Guinea Pigs only eat grass and other plants. It's important to give them some fresh fruit and vegetables. 

 Fresh drinking water should always be provided in a bottle, and food should be given in bowls, Guinea 

 Pigs will eat plastic!

     Looking after your Guinea Pigs

     Give your Guinea Pigs as much exercise as possible, and provide them with an outdoor run, but be sure

 to keep cats and dogs out of the way.

     Young Guinea Pigs are nervous. For the first few days, talk gently to your Guinea Pigs to build up trust,

  then slowly introduce your hands into the cage. Your Guinea Pigs will become curious and more

 confident around you. After a week or two, try picking up your pets using both hands. This is a good time

 to start feeding your Guinea Pigs something which should be done daily.
