I'm not really sure on his story.. but I do know the people who had him didn't have time for him anymore. You could tell by his coat, desperate need of a brush and bath. He had a few matts here and there, nothing bad though.
And he could stand to put 5lbs or so on.. you can feel his ribs, backbone, and pelvis a bit too well for my liking.
They fed him a crap food and said that he didn't eat. But he ate when I fed him.
Anyway, once we get him neutered, I don't think it'll take long to find him a home. He already knows his basic commands. He is a real snuggler, loves to cuddle.
Only thing I see 'wrong' with him is that he does have seperation axiety (with me anyway) and will cry and escape anything to get to his human. So a home where someone is there all day pretty much, will be preffered.
