CrazyMrJohn on YouTube posted a video of his interesting feline creation, showing his cat getting into the lift, sending it to the front yard and then waltzing out.
The lift uses infrared to sense when a cat enters through the catflap; once the itteh bitteh kitteh is comfortably settled in the glass box, the lift will slowly take it down to the ground, no human interaction needed.
Check out one cat giving it a go in the video below.
