Spherical pet toy

The utility model discloses a spherical pet toy. The spherical pet toy comprises a spherical outer shell, an inner shell, a motor and a power supply, the inner shell is arranged in the spherical outer shell and rotationally connected with the spherical outer shell, the motor and the power source are arranged in the inner shell, the motor deviates from a center shaft of the inner shell, a driving part of the motor is rotationally connected with the spherical outer shell, the power source is electrically connected with the motor, and when the motor works, the spherical outer shell is driven to rotate. The motor is eccentrically arranged, on one hand, the motor plays a role in providing power, and on the other hand, the motor can drive the spherical outer shell to rotate relative to the inner shell, so that the purpose that the spherical outer shell rolls on the ground is achieved, an eccentric balancing weight does not need to be additionally arranged, and therefore the production cost is reduced; meanwhile, th
