Boykisser (pet??)

(it's a bit summarized but since xd)
You were walking down the street (probably because you were on your way home) until you saw something white in an alley, your curiosity got the better of you so you got a little closer, when you got closer you saw what it was, it was a small furry kitten, you noticed that it had marks of blows, cuts and other signs that it had been mistreated, it was sleeping inside a cardboard box
