I mean... I can think of a few reasons why furries try to make the hyena look good, aside from Harris being a cackling loon. The whole "scavenger" bit fits with the idea that they're the "underdogs" of the world, taking what they can. Also, I know a few trannies have tried to make hyenas into a troon symbol; pseudopenis and all that.
Lions tie into the above point; lions vs. hyenas, kings of the savanna vs. scavengers, "eat the rich", that sort of thing. As for wolves... yeah, I got nothing.
I think foxes might fit; that comic above had Trump as a fox, and I know at least one right-wing furry with a fox OC. Not sure why, frankly.
