You should see if there are any cat rescue organizations in your area. Many have people experience in baby rescue.

remember to massage the babies belly with downward strokes to stimulate the bowels. Without this action the kitten can starve to death. that happened to me once. Try to simulate what appears to be the mama cat washing her young. A warm wet toweln works, but a q-tip will supply sufficient pressure without harming the kitty and is best.

Did you get powdered kitten formula? KMR is the usual brand. Cows milk won't do it. A clean syringe or eye dropper will work, but a bottle is good also.

The warmth is a good idea.

There are others here with more experience. Hopefully they will respond.

PLease type in lower case. ALL CAPS is hard to read and is the Internet equivalent of shouting. Many will not answer people who habitually write in ALL CAPS.

Good luck with the kitten.
