Pet chasing toy

A pet chasing toy, comprising:

• a main driving station comprising a driving unit and a main driving rotor, wherein the driving unit is arranged to drive the main driving rotor to rotate, the main driving station further comprising a main housing having a receiving cavity, a top frame connected to a top side of the main housing, the main driving rotor being coupled to the main housing and securely sandwiched between the main housing and the top frame, the main driving rotor comprising a cylindrical wheel having a groove circumferentially and indently formed on the cylindrical member, the cylindrical wheel having a pair of outer wheel portions, a middle support portion, and two connecting portions extending between the outer wheel portions and the middle support portion respectively, each of the two connecting portions having a circumference gradually decreasing from the corresponding outer wheel portion toward the middle support portion;
• at least one satellite unit which is arranged to be disposed at a distance from the main driving station, the satellite unit comprising a satellite driving wheel;
• a connecting cable extending between the main driving rotor and the satellite driving wheel, and being arranged to accommodate in the groove and frictionally engage with an outer surface of the middle support portion of the cylindrical wheel;
• and
• a visual object attached on the connecting cable, wherein the driving unit is arranged to drive the main driving rotor to rotate so as to drive the connecting cable and the visual object to repetitively move between the main driving rotor and the satellite driving wheel, wherein an outer surface of the middle support portion has a plurality of ridges so as to define a polygonal cross sectional shape for ensuring proper frictional engagement between the middle support portion and the connecting cable.
