I've seen the runt feed once. With the bottle and myself showing her a nipple on Mook (while fending the others off) the runt still doesn't eat. Its like it simply doesn't want to live. Is it common for a kitten to starve because it doesn't want/know-how to eat? I've done the whole warming/massaging thing to try to get the kittens blood circulating but in no time the kitten is cold and too weak or not interested in feeding.
So how often have you heard of the runt in a litter not making it during the first week? This little one is only a day and a half old...
