In this episode of ‘The Gadget Show’ Jason and Suzi are set a challenge to design and build a gadget that will appeal to animals as well as humans. Who can produce the most innovative and ingenious gadget for pets?

From a doggy treadmill to a flushing cat toilet, the duo endure animal mayhem as they test a selection of outlandish inventions in order to get some inspiration for their own builds.

Despite being allergic to dogs, Jason opts for an automatic ball-launcher that takes the arm-work out of playing ‘fetch’ with a pooch. The idea is that the dog retrieves the ball and places it into the launcher. It is then hurled 30 metres and the process begins again. Because of her love of cats, Suzi decides to build a gadget for moggies. She always wonders where her cat goes when it disappears through the cat flap, so she develops a GPS tracking device and camera for cats to wear on a harness.

Jason heads off to a dog show to see if his device has the audience begging for more, and Suzi tests her purr-fect invention with TV vet Scott Miller and his cat. Which invention will be a hit with the pets and their owners?

Also this time, Ortis heads into the woods with ex-special forces hard man Mike Hawk to test the best pocket tools on the market. Jon, meanwhile, trawls through the top online photo-printing services available.
