A serval is a cat native to the African grasslands typically found south of the Sahara Desert. The cat has a lean body and the longest legs and largest ears of any cat breed. Their coats are predominantly shades of tan or orange with black or dark brown markings. The coat pattern helps the cat disguise itself when hunting in tall grasses. The serval is a solitary animal that can live around 20 years.
