Okay, y’know what, I actually got you (if you mean legitimately a “pet” as in an actual animal)
Though it’s not powers, there’s supernatural shenanigans going on. The animal thing happens later, but this is a surprisingly fun/weird read

There is some new manga as bl- boy being bird
Or girl happen to be raven/ cat in straight stories
Im looking for a bl or even straight to manga where the bottom become the pet, and if there is like powers, like magical powers involved too that's great
