From what I have read, male gray foxes can be rabies carriers, seldom getting very sick, able to reproduce, etc.
That said, any mammal can get rabies, as far as I know. Never heard of a whale or a porpoise getting it, though...
The Cape Cod orca (AKA Ted Kennedy) has been known to frequently foam at the mouth.
I've heard that they can get it only accidentally, but never on porpoise.
