Adult mice typically weigh about 1 ounce (28 grams) and are approximately 2.5 to 3.5 inches (6 to 8 centimeters) long, not including the tail (see Mice: Mice at a Glance). Male mice are typically larger than females. Pet mice are available in many colors and coat patterns due to specialized breeding. Coats can be smooth, curly, longhaired or a combination. The most common color variations include brown, black, tan, gray, and albino, with lighter and darker shades of these as well. The usual life span of mice is 1.5 to 2.5 years.
