Norwegian Forest Cat kittens & cats in Cape Girardeau, Missouri

We found this little guy on the side of Route 60 in La Center, KY. We have already made attempts to find his owner. The area of road he was at had no nearby residences and he was very clean for an "outdoor cat" or "stray". Its hard to imagine someone intentionally abandoned him there as he seemed pretty fixed to that spot by the gaurdrail on the shoulder. He was timid and hid in some thistley branches, when i first came crunching up on the dry leaves but as soon as i called to him (in the usual kitty cat fashion) he came out pretty quickly and then right up to me. As i drove back to work with him he sat in my lap and purred and drooled (he was very happy/relieved). He was all skin and fluff at that point. its been about 2 weeks and ive gotten some weight on him (im sure the tape worm de-wormer might've helped). I also gave him some stronghold drops for fleas and other worms. He has gotten along very well with my other cats and is very cuddly and playful. If i didnt have 12 others...
