Since he was found by a highway and was obviously someone's pet I certainly hope they are putting the word WAY out there... If I lost kyra or tucker while traveling and didn't hear that someone had found them... I would be heartbroken. Godspeed to mr. Adam in finding his way home.
I hope he finds a good home, with someone who's educated enough about cat nutrition and will continue to feed him raw meat...no transition time or hassle involved. It would be a win win for the cat and owner. But, all things considered, the important thing is he survived and is now safe.
