If you cat has stopped eating it may be ill. Please take it to a qualified animal doctor (a vet) to see what is wrong with it and have it cured.
Gatorade is healthy to a point...........the doctor I work for says one a week is good to keep healthy electrolyte balance. It is also good for people that are sick on a no eating diet or who are losing fluids out one end or the other. The reason for that is water can cause more dumping of all the good things. The sugar sports drinks are absorbed more when going through the digestive system.
Yes by moving them with out eating them
No you shouldn't starve yourself.
Although water is the best way to stay hydrated, there are other methods which will work almost as well. There are sports drinks such as Gatorade, but they can do more harm than good. try eating watermelon or cucumbers before running. both of these fruits are high in water content
