Cats are interesting animal.

Sometimes, it's just like a wave upon the sand -- you cannot catch it forever ! Like moonheam--no one can hold it in his hand . Always lively , never fell tired . But actually , if you want to find a word which can describe them , the best answer is 'as cute as a little girl , kind but naughty .' Their eyes will become green at night . They like fish very much . Fish are just thier life ! Cats also need people to take care of them . They ' re so lovable that there are so many people 'd like to feed them , and play with them .
