One of the most amazing things is how forgiving animals can be, even after humans have done terrible things to them. Horribly abused rescue dogs overcome anxiety and learn to love again all the time; but, for whatever reason, you don't hear about cats bouncing back quite as often. That doesn't mean that it's not happening.
This cat in particular had a very tough time, and although his predicament left him crippled for life, he's still learned to love again.
He's ten years old, and he sits differently from most cats because his bottom half is completely paralyzed.
