Space cat

a totally regular cat and not an eldritch creature who lives in space! this normal cat has a helmet on, a trait he's observed his human housemates on the space station always have, and he just has to match. one day when the astronauts when up to the space station, he was there! casually having moved in to see more of the humans who kept peeking into the space he totally doesn't live in. his arch nemesis is space mouse, another totally normal creature who moved into the space station with him, they engage in various tom and jerry like shenanigans, the rivalry is really just for show, the two are close and mostly play hate eachother. the mouse also has a helmet. they are both very normal animals from earth
