when she came to my house at first she was really thin, now she looks kindda fat, I normally fill her bowl everytime it looks empty or everytime she comes crying to me that is empty even during the night, if I dont get up and feed her she will hop on my pillow or run across my pillow to make me to get up, and to me she looks now heaveir than most cats I see, now picture that running across your pillow, any ideas? should i feed her only during the day?
