1.) It's a surprisingly soft answer, but Huey misses the colony of cats that he used to care for. He was a lonely kid, so the cats not only gave him companionship, but a purpose as well. They lived a peaceful life on the docks near his home and he fed them daily. When one of them was ill or injured, he took them to a little infirmary he set up in his bedroom, and nursed them back to health. Some of the cats would follow him around the city, which unnerved the others. There he was, a demon spawn strolling about with a gaggle of beat-up looking stray cats. Kid's shady.   2.) I can't give you those details. It's a surprise.   3.) Huey was thirteen when he witnessed someone dying. He and the small group of friends he had jumped a drunk merchant in an alley. They wanted to take his coin purse and run, but unfortunately Huey's demonic heritage wasn't going to let it be that simple. Plus, why take his coins when they could take all of his valuables? While his friends left with the gold, Huey beat the man to death with a brick, and then took all of his shit. He felt no shame nor guilt. Nope, just excitement and a sick sense of pride over his "trophies".
