Kiki needs to see a vet ASAP. Unfortunately cats can develop a fatal liver disorder if they don't eat! Please get her help immediately.
Be sure that Kiki has her own space in a room with a door that will close. She should not be allowed to come nose to nose with the dog at this point. She will feel far more secure if you can give her a room of her own with food and a litterbox for at least a week. Then gradually let her explore the new territory. Get a baby gate and isolate the dog while she is out exploring! She can sniff the dog through the gate and get used to him.
