Depending on the type of prey which they hunt, servals can hunt both during the day and night. If they are living close to the humans, they sometimes hunt domestic animals, like chickens. Servals use sharp claws to catch different types of prey: rodents, squirrels, fish, frogs, snakes, small birdsâ¦ Servals are very successful hunters - they catch 50% of their prey. Other cat species have only 10% success rate (catch only one animal in 10 attempts).
