|Kat's first invention; this is seen in "Let the Games Begin", where Coop is almost crushed by a huge boulder!. This was set up by Kat to crush Coop in return for blowing up his Alien collar.|
|Added by Coop+KatThis is seen in the "Me-Oh Me-Oh Meow" episode; Kat, tired of his new collar, manages to get it off and then modifies it so it can torture Coop. 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 is Kat's second invention; it is seen in the episode "Do Not Fort Sake Me" when Kat tries to communicate with his home planet. The device is made out of ordinary household items such as a cookie tray and metal tong's.|
|Added by HugeKidvsKatFan
As seen in the episode "Nip/Duck", Kat built this to resharpen his claws after the Vet trimmed them down; this device is also made from everyday household items such as a blender, cheese grater and an orange juicer.
|Added by HugeKidvsKatFanAs seen in the episode "Search and De-Toy", Kat built this rocket in an attempt to send food back to his home planet; the rocket is made out of ordinary household products such as a blender and a food funnel.|
| This is also seen in the episode "Search and De-Toy"; seeking revenge upon the RC Helicopter, Kat modifies a TV remote and turns it into a remote control for the RC Helicopter. Kat thought that Coop interfered with the rocket on purpose so he decided to take control of the RC Helicopter and crash it into Old Lady Munson's yard. 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 Formula
|Added by HugeKidvsKatFanThis 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. As the audience, the exact ingredients of the Sleep Formula are never revealed, this is probably to keep us wondering about what it could be made of.|
Potion of allergyEdit
|Added by TheGabrielZaumIt is seen in the episode the Allergy. Mr. Kat invented this for Coop's father thinks he's allergic to Coop. He did it with hot sauce, powder pica pica, poison ivy, bottled pepper and onion.|
The evil warrior MegazurgEdit
|Added by TheGabrielZaumAs seen in the episode Just me and Glue. Kat changed the warrior Lord Megazurg to attack Coop. But he goes is "The Backfire" when he discovers he also wants to destroy it, so Coop and Mr. Kat work together to destroy it.|
Pencil Sharpener of DoomEdit
|Added by Coop+KatIn "How the Test Was Won", Kat fixes Coop's pencil sharpener to make it attack him by eating all the pencils and then spiting out all the erasers and metal parts.|
its the blender thingyAdded by Coop+KatIn "One Big, Happy Family", Kat creates a machine to mess up Coop's body, or "scramble his face". Coop soon figures out who made it, and detonated it. Somehow, when they get home, Kat manages to get it back. No one knows how he got it back, especially with Millie next to him 24/7!
Unknown food spiceEdit
In "One Big, Happy Family", Kat puts an unknown spice on Millie's cupcakes (rumored to be food poisoning.) This was probably a trap for Burt or a way to torture Coop, since Burt told him to sit in the corner on an old bar stool and not move. Watching your nemesis make poison (if that's what it is) and have your family almost eat it and die, Kat knows Burt and Millie are Coop's only family after something (might have) happened to Mrs. Burtonburger and she probably won't be able to find Coop or have Coop find her.
Added by Coop+KatIn "One Big, Happy Family" Kat makes a trap for Burt and or Coop since if Coop tried to save Burt, Coop would be grounded or if he was too late he would be grounded, but Millie took the bait and both Kat AND Coop rescued her. Coop was (possibly) grounded.
Locked Storage CellEdit
Added by Coop+KatIn "Play N'Ice" we learn that Kat has a secret cell where he hides all his cat food. The lock to his food cell is voice activated. It was seemingly destroyed when it and the ice castle collapsed on themselves.
Monster Plant Juice: It can turn plants into monsters. Ingredients include ketchup, mashmallows, and Kat's hairballs. It also smells horrible.
