The Chausie is a large cat with heaving boning, full broad chest, and strong musculature. The legs are moderately long. The head is slightly longer than in other domestic cats, which makes the Chausie look like a cougar. The large ears are set wide and have tufts on the tips. The tail is slightly shorter than the entire body length. The eyes are almond shaped.
Adult Chausie males weigh 9 to 15 pounds. Adult females are usually 7 to 10 pounds.
