Hi... My son brought in a stray cat. It is a beautiful long hair female. We were looking into spaying her when we noticed she was gaining weight. Well she was pregnant. She had 9 (yes 9) kittens 4 weeks ago. They are really cute. All were doing well until last night. Three of them died. We are not sure why. Two of them were runts but the third one seemed to be doing okay so I am not sure what happened. The other six are doing great. Does anyone have any ideas why this could have happened and should I be worried about the other kittens.
