Personality
Katter is known for being scatterbrained and being bullied by her chat. Her chat loves to spam sound alerts and redeems (as well as breaking the TTS for hilarity). She is relatively easy to jump scare when playing horror games but regardless of what game she plays, she has difficulty staying focused on the task at hand, typically becoming lost (even with a map) and being distracted by seemingly random things.
Most of her streams feature sections where chat distracts her from the game with in-depth discussions and impromptu questions. These moments are so distracting, her art streams are rarely productive.
Appearance
Her appearance features primarily blue and green gradients adorned in glittery sparkles. There is a running joke within her community about her being blue however, her body is primarily a pale green. Her "hair style" changes with various models but her original design features a long slime braid over one shoulder. Regardless of the changes, a primary design that does not change is the slime dripping down over her face to cover her left eye. It is canon lore that she does not have a left eye.
True to slime inspiration, her appearance changes relatively frequent with little warning. Though usually these changes are due to her love of memes or humor in general.
Background
Katterbox streamed in-progress art commissions where she encouraged clients to request changes live. Following complaints about some sites not being open to a wider global audience, she began researching twitch. Her first stream on Twitch was on 23 November 2018.
Trivia
- She is married (happily! <3). Her husband (Maverick or "Mav" for short) frequently shows up in chat and sometimes joins in games.
- She currently (as of May 19th, 2025) has 4 cats. Two of which were adopted from a cat cafe while the others were feral prior to joining her family.
- When asked, she refers to herself as an "Ectoplasm Slime" or "Ghost Slime" but usually she talks about the oozes and mimics from D&D 5e as inspiration for her design. As well as "schrodinger's cat" being the inspiration for her username.

Around the 31st May, she was officially introduced to Vtubing software and began to stream with her own models. Her streams began to include more video games as well.
2023
This year, her streams became more erratic due to home emergencies and a death of housemate. She cited work scheduling as the reason for the hiatus as well.
