my missing cat (new cat coming soon??)

so i haven't really addressed this online, but there's something going on with one of my cats. for those who don't know, i have two cats, one is named miles (the one in the first image) and paipai (the one in the second image). i’ve been with both of them since i was 5 years old. for the past few weeks, paipai got missing and i tried going to an animal shelter to see if they found her, but they didn't. however, i do think i'm gonna get another cat soon, so what do you think they'll look like? but to paipai, you'll forever be missed... :(
