If my cats weren't asleep right now, I'd hug em. I have two strays who were abandoned just like this, and both looked like they were malnourished. Took em in, cared for them, and they're healthy and happy as can be now. I don't care if they try to redeem the previous owner in this series; that owner is a piece of trash and will always be. There's a special place in hell for people who move and leave their pets behind like that.
