TSONCOLE USB Pointer Pen Rechargeable Laser Toys Interactive for Cats Catch Teasing Scratching Interactive Exercise Training Tool

It has a switch rather than a button you have to depress continuously whilst you entertain your furrbaby. Plus the USB means more hours of play because I don't have to remember to have back up batteries (or deal with recycling them).

Love that this laser pointer actually KEEPS the light on instead of having to hold it down. Also does the USB charging so don't have to worry about getting those tiny batteries.
