My Mama gave birth 5 weeeks ago and I am not sure what I should be feeding her? Since I found out she was pregnant I have been feeding her milk to drink and Iams kitten food. I notice that her BM's are very runny, should I not be giving her milk? The kittens are now 5 weeks and I notice that they are also eating and drinking her food, is this ok? Thanks, Kimberlee
