Answer
Dear Burt,

If you can't take it to the vet, the only thing you can do is keep it warm and make sure it has easy access to food and water.  The right vet would be able to give it a topical parasiticide which might or not help it pull through.  It also could be sick with other things too.  Be sure to wash your hands (both before and) after holding it and especially before touching other animals.

Best of luck to the little thing.
