The bobcat (Lynx rufus) is a captivating wild cat found across North America, from southern Canada through the majority of the contiguous United States and into Oaxaca, Mexico. This adaptable predator inhabits diverse environments, including woodlands, semi-deserts, and even urban edges. Understanding the physical dimensions of this elusive feline provides insight into its role within these ecosystems.
Core Dimensions and Weight
Bobcats possess a compact, muscular build, well-suited for their predatory lifestyle.
An adult bobcat typically measures between 18.7 to 49.2 inches (47.5 to 125 cm) in length, including its distinctive “bobbed” tail, which itself ranges from 3.5 to 7.9 inches (9 to 20 cm) long. The average total length is about 32.6 inches (82.7 cm).
When standing, a bobcat’s shoulder height generally falls between 12 to 24 inches (30 to 60 cm). In terms of weight, adult bobcats usually weigh between 14 to 40 pounds (6.4 to 18.3 kg). Despite their relatively small stature compared to other wild cats, their dense fur and prominent ear tufts can sometimes make them appear larger.
Factors Influencing Bobcat Size
Bobcat size is not uniform across their wide geographic range, with variations influenced by several biological and environmental factors. A primary determinant of size is the bobcat’s sex, as males are consistently larger and heavier than females. Adult male bobcats typically weigh between 18 to 35 pounds and measure 32 to 37 inches in length, while females generally weigh 15 to 30 pounds and are 28 to 32 inches long.
Geographic location also plays a significant role in bobcat dimensions. Bobcats found in the northern parts of their range, such as Canada and the northern United States, tend to be larger than those inhabiting southern regions like Mexico and the southern U.S. This pattern aligns with Bergmann’s Rule, an ecological principle suggesting that larger body sizes are often found in colder climates, which can help with heat retention. Research indicates that latitude and elevation are associated with variations in bobcat body size.
Comparing Bobcat Size
A bobcat is considerably larger than an average domestic house cat. Bobcats are typically two to three times the size of a house cat, with an average bobcat weighing around 25 pounds, whereas a domestic cat usually weighs between 7 to 15 pounds. A bobcat’s average length of about 37 inches also far exceeds a house cat’s average length of 18 inches.
The bobcat is generally smaller than its close relative, the Canada Lynx. Canada Lynx typically appear more substantial due to their longer legs and larger paws, which are adaptations for navigating deep snow.
