The bobcat, Lynx rufus, is a medium-sized wild cat found throughout North America, thriving in diverse habitats from dense forests to arid deserts. Understanding the typical size of a bobcat and the factors that influence its dimensions can provide insight into this native predator.
Typical Physical Dimensions
Adult bobcats possess a muscular and stout build. The average weight for a male bobcat is approximately 9.6 kilograms (21 pounds), though individuals can range from 6.4 to 18.3 kilograms (14 to 40 pounds). Female bobcats are generally smaller, averaging 6.8 kilograms (15 pounds) and typically weighing between 4 and 15.3 kilograms (8.8 and 33.7 pounds).
From the head to the base of its distinctive short tail, a bobcat’s body length averages about 82.7 centimeters (32.6 inches), with a range spanning from 47.5 to 125 centimeters (18.7 to 49.2 inches). The shoulder height of an adult bobcat typically measures between 30 to 60 centimeters (12 to 24 inches).
Variations in Size
Several factors contribute to the variations observed in bobcat size across different populations. A primary influence is sexual dimorphism, with males consistently growing larger and heavier than females.
Geographical location also plays a significant role in determining a bobcat’s size. Bobcats inhabiting colder, more northern regions, such such as eastern Canada and northern New England, tend to be larger in overall body size. Conversely, bobcats found in warmer, southern areas, like the southern Appalachian Mountains, are often smaller. This pattern is linked to environmental conditions and resource availability.
Size Compared to Other Cats
The bobcat is notably larger than a typical domestic house cat. A bobcat is generally two to three times the size of a house cat, which usually weighs between 2.3 to 6.8 kilograms (5 to 15 pounds). While a house cat might average 46 centimeters (18 inches) in length, a bobcat’s average length is closer to 94 centimeters (37 inches).
When compared to its larger relative, the Canada lynx, the bobcat is generally smaller. Canada lynx typically weigh between 8 to 20 kilograms (18 to 44 pounds), often exceeding the average bobcat weight. Although similar in appearance, the Canada lynx tends to have longer legs and larger paws, contributing to its more substantial appearance.
