Gizmo, being a very scientific feline, is known to have performed various experiments that some would consider to be unorthodox. Though most of his experiments are performed on others, he himself has never shied away from being poked and prodded in the name of progression. As such, this has led Gizmo to become fitted with several modifications, most of which cannot be seen from the outside. These upgrades are usually for his own benefit, allowing him to work harder and longer, while others are just for his own amusement.
