Some moron left a box of kittens (app. 6weeks based on size). The kittens bbite off nipples on bottles so that led me to believe they are weaned. I tried mixing kmr with kitten food and letting it soften and they want no part of it. They lapped up a little of the liquid but won't eat the mush. Is it they are eating a different brand or what? They drink water from the dish and use the litterbox but not eating will make them go downhill fast. What can I do to help these babies?
