It's a tad long, please hear me out though. My fiances cousins cat had 4 kittens, she nursed them for 2 days and was then hit by a car. I knew these kittens were not getting the proper care because they were always cold, wet and they had them eating baby formula. Finally about a week ago I went over there to find the kittens on the dining room table almost dead, all in their own feces. I asked who the heck was taking care of them and no one knew or cared. I tried feeding them to then find out 1 was already dead in the corner of the box. So I fed the other 3, one of which was on the brink of death. Since then they have all passed except one. I wanted to take them sooner but I have 2 cats of my own and I live with my in-laws. I was not expecting to take in these cats but when I saw their condition I HAD to. The healthy kitten, I put on KMR formula, gave her a bath, have been rubbing her bottom when she has to go potty, waking up with her whenever, the whole 24/7 and I am hoping she's going to make it. BUT. A few days ago we ended up giving her about 2-3 drops of mineral oil and later on that night she pooped. It was a normal color and whatever. She hasn't pooped in a few days and then yesterday and today she has been having diarrhea. Not a lot at a time and it is runny and an orange color. I was feeding her KMR mixed with a little warm water, now I have switched to straight KMR, no water and have been feeding her a little less. I do not have the money to take her to the vet, as she is a rescue. What can I do to get her diarrhea to go away? Thank you very much if you read this and please help me.
***She will be 3 weeks old on Friday.
