A filing device that allows an animal to have its nails trimmed without human interaction or interference. The filing device includes a casing, a rod, a wall, housing, cap, motor, motor cover and power source. The rod is concentrically nested within the casing and covered in a grit material. The casing has a cutout on its bottom or top surface that allows the rod to be exposed. The rod is powered by a motor and when the power is turned on it causes the rod to rotate. An animal may mount itself on the casing of the filing device. When the motor is turned on it vibrates the device which causes the quick within the animals vein to retract. As the animal sits on the casing its nails are exposed to the rotating rod which causes the nails to be filed.
