Here's some info on B12 as an appetite stimulant in cases where a cat hasn't eaten for a while (there was a Texas A&M Vet study done on this):

That study supports what you did with Shango to kick start him into eating. The study attributes the B12 stimulant efficacy for cats who might be suffering from B12 deficiency due to trauma, stress, or illness.
I see no reason to believe that administration of B12 will stimulate the appetite of an otherwise healthy cat, other than for the reasons stated above, where the extra calories will be quickly burned off due to increased activity.
In post #25, I was talking about a healthy, non-traumatized cat. Apologies for any misunderstanding, and the efficacy of the B12, according to the study "might be" proven in cases such as yours.
