Panthers roam the American west, Florida and a few other parts of the United States, as well as much of the rest of the western hemisphere. Females weigh up to 100 lbs., while males may reach 160 lbs. Both males and females display a tawny brown coloring with off-white or cream undersides. Contrary to folklore and popular misconception, there is no recognized species of black panthers.
While panthers remain on the endangered species list, bobcats thrive in many parts of the United States. Arizona alone has an estimated population of 30,000 bobcats. Much smaller than their panther cousins, bobcats range up to 25 lbs. in weight. They sport a short, dense brown fur with black spotting, a banded tail and tufted ears.
Panthers roam an area as large as 200 square miles, while a bobcat's territory covers around 15 square miles. The larger cat prefers forests, mountains and swamps, where sufficient cover can hide its mass. The small bobcat, on the other hand, enjoys a wider range that includes prairies, scrubland and desert brush. Since the animals are natural stalkers, they rely on ground cover to avoid being seen by their prey.
Large mammals such as deer and wild boars make up the greatest portion of a panther's diet. Panthers will often fast for several days between kills. When large game is scarce, they dine on smaller mammals. Panthers and bobcats usually avoid humans. Bobcats prefer birds, rodents and small mammals. Both types of cats gorge on a kill and hide the remains under dirt, brush or leaves for later use.
Bobcat males reach sexual maturity at two years of age, while a panther may take three. Females attain maturity earlier, at between one and two years for a bobcat and about half a year longer for a panther. Spring is the most active birthing period, although both species may bear litters throughout the year.
Panthers bear from one to five kittens after a gestation period of between 88 and 98 days. Bobcats gestate in 57 to 65 days and bear from one to eight kittens in each litter. In both cats, the average litter size is two to three kittens.
If you encounter a bobcat or panther, do not run. The animal will likely leave the area. If it doesn't, make yourself appear as large as possible by opening your jacket or raising your arms. Speak firmly and move slowly. Stand your ground to demonstrate that you are not prey. If you crouch or drop to the ground, you will appear more vulnerable. Fight off an attacking animal with rocks, sticks or even your fists. These tactics have proven successful in the past.
