Cool stuff. I got a fox face for christmas. The fox face is basically just the hide of the face with eye mouth and ear holes. No other taxidermy specialness.
Anyways I introduced to my pet rabbit (which my wife insists is very cute) and it totally freaked. I tried it a couple of more times and tried to make it's environment otherwise comforting, however, it still FREAKED, sprinting back to it's cage.
Interesting since this rabbit has never even been outside. I would take this to mean that the scent of a fox INSTINCTUALLY freaks out rabbits. The fox is a rabbits number 1 predator, in some habitats, and it's urine scent is actually sold as a rabbit repellent. Is it possible that this repellent works on rabbits even if they have never smelled a fox previously? Perhaps it similar to the instinct that I have that poop stinks. Not that poop is my predator but that it is associated with disease.
