There was a fellow who set out to prove his theory that wolves in the great north lived mostly on mice and other small prey, and claimed to have lived for a year himself, consuming nothing but mice, just to prove it was an adequate diet for "large animals."

One might suppose he could offer a fairly authoritative opinion on the nuances of mouse flavors.

There is the possibility of some bias, however, since he reported the easy capture of sufficient mice because they were eating all the stuff he brought to his remote cabin - and would otherwise have eaten, so the mice he ate may have been on an atypical diet not representative of the finer points of "wild mouse" flavors.

Based on significant observation of cats, and experience with satisfying the dietary preferences of same, I would venture that the idea that cats (in general) have any sort of preference for "mouse flavor" is not particularly accurate. My observation is that cats will eat, with a degree of apparent relish, anything that wiggles. Mice are among the larger "wiggly things" consumed by the typical house or barnyard cats, but cockroaches, spiders, houseflies, horsefiles, earwigs, cicadas and almost anything else that "runs" and can be caught apparently is equally tasty. Our own cats showed a pronounced liking for rabbits (cottontail) for a time when the had access to them, although (fortunately) despite their best efforts I don't believe any ever managed a squirrel.

Only the cat the caught the mouse generally will eat it. A dead mouse is of absolutely no interest to the other cats in the household (usually).
