When I was a little baby hunter, back in Vanilla, and fresh from Runescape, I was just about to go tame my very first "real" pet. Some hunter came along the path and said "make sure you tame a good cat over there" (I think he was meaning the dark striped level 8-9 tigers). However I'd just "abandoned" the white spotted black (which tbh looks like a gorgeous white spotted blue cat on my screen, and always has) cat from my hunter quests and I'd sworn to him I'd re-tame him because I get attached like that

So I ended up re-taming the same Nightsaber Stalker I'd picked up previously, and I named him Karma. I remember I was really unhappy with the name and was contemplating ditching him, but I didn't know that you couldn't rename them back then so I kept him thinking I'd just change his name later. And by the time I'd thought of a nice name for him, which I forget, he was already my "Karma" and I really couldn't see myself changing it. So it never bothered me since.
I don't know if they're still there, but back in the day I even left glowing reports over the Nightsaber Stalker pages on Thotbott and stuff with screenies of him as he levelled... so that was cool. I kept him through his life mainly because I think all we had were 3 stable slots, and I didn't really have the room/inclination for anything else, though I do remember being very taken by the Warp Stalkers (I've picked once up now we have the room) which I owned for quite some time... My second "perma" pet was Skoll, though, so that's how long Karma and I rode solo. It wasn't really until our stables were increased that I started "collecting" pets. I now have some that I really really love, such as my warpstalker Toothless and my orange Tol'vir tiger Flint, but at the end of the day it's always Karma I turn back to.
