Thanks for all of the helpful replies everyone!
I forgot to mention that I took her to the vet already for a check up yesterday. The vet she said she is perfectly healthy out side of that problem. So she suggested to put Vaseline on her bottom so that the bm wouldn't stick. I know about hypoglycemia and I leave food and water out for her at all times. I also just bought nutri-cal. She is also drinking and eating well. The vet also gave us some food, Medical, so that she would grow healthy and strong. Her bm is soft probaly because she is just getting use to us and that we are switching her food slowly as the vet suggested.
I will definitely trim more hair around her bottom.
I will post more pictures of my baby soon.
Thanks again!
