Minecraft – Where to find iron

I recommend installing the damage indicators mod because it displays mobs health at the top left, but never the less the health of the cat starts at 5 hearts of health so 1/2 a players. Depending on the tier of the pick it deals different amount of damage same goes with swords. The cat does not regenerate and is hardish to heal. Here is a quote from the gampedia website on how to heal the cat. "Cats cannot be healed by being fed fish, unlike tamed Wolves with meat. The only way to heal a cat is to use a splash potion of Healing or Regeneration on it." I wish you best of luck with your cat :D!

The conventional method for finding an End Portal is to use Eyes of Ender (Combine Blaze Powder with an Ender Pearl). When used, they will float up in the direction of the closest End Portal, then after a few seconds, either fall back down, or break.

Once you get within a certain range of an End Portal, the Eyes of Ender will then float down toward the ground. This is where you can start digging, as the Eye of Ender will (generally) indicate you are directly above the portal.

As for using the "x-ray glitch" and "digging out the entire area", an End Portal is a rare occurrence. If you managed to find one near your spawn (say, within 64 chunks) you'd be incredibly lucky.
