About nine
o'clock
Bella and the rat were great friends . It was very funny to see them going about the house together . From the very first she had liked him , and coaxed him into her cage , where he soon became quite at home , -- so much so that he always slept there . About nine o'clock every evening , if he was not with her , she went all over the house , crying : `` Davy ! Davy ! time to go to bed . Come sleep in Bella 's cage . ''
