You cannot catch Mew in the Cerulean Cave because it can't be found there.
You can get all the Pokemon in the cerulean cave where you find celebi below the cerulean cave.
You can find Mewtwo in the back of Cerulean Cave.
The Cerulean Cave is located in the west part of Cerulean City. If you head north, you will notice a water way to the left of the bridge. Surf on that waterway and you will eventually reach Cerulean Cave.
