Phantomcatgender catgender identity in which one's gender is related to cats and phantoms and/or similar creatures. This may include the aesthetic of these creatures, darkness, dark colors, nighttime, and similar features commonly associated with phantoms, as well as feeling strongly connected to cats. One's gender may or may not feel like a mutant mix of a cat and a phantom-like creature, or a darker and more spooky/monstrous form of a cat.
Depending on what the user of the term considers a phantom to be, the term could also be considered a minecraftgender to users who feel that their gender relates to the phantom mob from minecraft, a gamegender to users who feel that their gender relates to the phantom from the game Animal Jam, and so on. All of which would still suit the term phantomcatgender so long as the individual feels that their gender is also connected to cats.
