Coop CollarEdit

Kat had become tired of his new collar telling him what to do all the time, so he did all he could to get it off; once he did, he figured it was the perfect opportunity to torture Coop with it. The collar is nothing more than a modified pet collar, the only difference is it now has a human. function in addition to dog's and cat's.

This device is nothing more than a modified TV remote; it is now able to pick up the RC Helicopter's frequency and wavelength.

Kat's Sleep FormulaEdit

This is one of Kat's more advanced inventions; it is seen in the episode "Flu the Coop", to put Coop to sleep and keep him from covering Kat in his germ's. The contents of Kat's Sleep Fromula might be comprised of soothing ingredients or it could just be made of a very powerful sleeping agent found on Earth or probably Planet Catnip.
