The present invention relates to a system for sensing an animal behavior using a touch sensor substrate, and a behavior analyzing device using the same. The system for sensing an animal behavior includes: multiple touch sensors arranged in a space (cage) in which a target animal is living in a constant specific interval; and a touch sensor controller transmitting signals detected from the touch sensors to the outside. The system for sensing an animal behavior and the behavior analyzing device using the same by the present invention can accurately classify the movement and various behavior patterns compare to existing methods.
