The great jaguar stares at the wrapped plastic boar's leg. There is a moment of careful consideration in this regard where the plan nearly goes wrong. Where the jaguar understands what you are holding and its impatience to have it from you nearly results in it going from tense to leaping, ripping your arm off, and tearing into the boar's leg. It does not, however, for whatever mysterious reason only it knows. But it makes it obvious that it had considered it and determined not to do so with a slight flick of its ears and an easing of its tension.

When all the plastic is dropped and the leg emplaced, it watches you until you stop moving. Then it watches you for several more seconds to see whether or not you intend to start moving. Then several more seconds to check again for certainty. After a moment, when it has determined that in fact you will not move, it leaps down from the branch with a practiced ease that allows it to maintain eye contact with you during the entire movement, its head never actually turning away from you. And then it bends carefully to the leg and begins eating, maintaining vision of you while it does so, taking careful, almost dainty bites from the meat. 

While this may not be the most pertinent factor, you may note that scans from the revealed teeth as the great jaguar goes to eat indicate that its bone structure also contains metallic elements in unusual amounts. Rather than the expected calcium and phosphate with trace iron, you're detecting much larger amounts of iron, representing a few full percentage points of total bone mass, and there also appears to be a magnetic element, likely cobalt.
