The electric skateboard that I built for my cat MIDI has a throttle lever with a hole in it where treats go. Put a treat into the throttle lever, and she pulls it to get a snack and give the board a boost.
The board was prototyped and built with the Glowforge for custom housings/parts, scavenged bits from electronics/store, some off the shelf electric skateboard drivetrain components, DC motor, and a Adafruit Feather microcontroller.
