Can a red fox and a gray fox mate and produce viable offspring?

This implies that it is NOT possible (see second post). This says they do not cross breed in the wild, but that is kind of vague . . . and doesn’t answer the question of viable offspring if they were breed in captivity. Finally, this implies it might be possible . . .

I think you saw a variation or mutation and not a cross-breed.

Here’s a taxidermy of a red/grey mix

I saw two with gray bodies and a red face the other evening. I figured they were juveniles but do not know for sure. Did yours look like these two ? (Single click any picture and it will come up larger.)
