A. It does not sound too good, complete loss of appetite at this age with massive loss of weight is difficult to rectify. Did you try giving her milk replacement for kittens? you should give it a try. Any sign of diarrhea prior to the loss of appetite? that could indicate an infection, in this case she needs to see a vet ASAP to receive treatment.
Some kittens are unfortunately born with congenital diseases and some of them will not survive the first few weeks.
A. Try putting some formula into a small bowl and encourage her to lap it up. If she is not quite ready you can bottle feed and then transition her to this. You should also contact your vet about deworming her. She may have a heavy parasite burden that prevents weight gain and decrease overall health.
