The size disparity is extremely striking. But hypothetically, it is possible for a giant male tiger weighing 375 kg to encounter a petite female mexico jaguar weighing 45 kg. The jaguar would be like a house cat in comparison to the tiger. However, the situation would be reversed if a petite tigress of 80 kg met a large pantanal jaguar male of 130 kg (albeit there would not be as much of a difference as in the first scenario).
