If you live in a cave and you're having problems with the mobs spawning, then just make a room with a crafting table, furnace, furnace floor, hole that goes to bedrock, and 2 doors (1 in cave, and 1 leads to outside the cave in case you leave the mobs for later. If you want a pet, then first have a test animal, close him in the cave, but you obviouslt can't completely seal it. So just put lots of trapholes outside in case he escapes, then keep trying until he has no escape, then he could be your pet or not. If you're cave is too small, then make an upper room instead of having to look for blocks and make a room, this just requires breaking. I have no more cheats, but for more i will make a part 2, and try the seed:hunt. It is my main seed, flat big land, snow, giant cave (my home with a chicken), and others.
