WereGato is canonically a feral form that Talia takes during Halloween. (Any Anthro WereGatos are non-canon.) Due to a glitch in her data, her tail ring keeps her from digitally evolving along a traditional pattern but can allow her to manipulate her form. She can enter WereGato mode during the months of September and October for fun, just as a different form but retaining her wits. But she also can be triggered into entering it without her will through a traumatic event or something similarly shocking to her system. Her friends have long ago learned not to scare her! When entering into this form that way she is often in a sort of fugue state where she is acting primarily on survival instinct. Think of it as similar to a berzerker.
