Meet the Petronics Mousr: an interactive robotic mouse that is smart enough to sense and react to your pet. It has 3 play modes but you can also control it from your smartphone. Mousr has a tough polycarbonate shell and replaceable tails. It works on carpet and most common household surfaces.
Mousr uses navigation, cat proximity, and orientation sensors to avoid obstacles, sense approaching cats, and detect when it is behind held.
