It is not possible to actually make a mob spawner in any version of minecraft. Mob spawners are only obtainable via in-game commands or if you use a mod of some sort.
You can get a mob spawner in Minecraft by using any pickaxe (except wood) with Silk Touch 1 enchantment or by spawning it in (Dec:52).
You cant find a giant mob in vannilla minecraft but you can sumon him using a command or a spawner.
Maybe your game level is on peaceful or you put torches around it.
If you are looking for a way to pick them up, well, you can't pick mob spawners up. You can only destroy them with a pick but it can give you a lot of exp.
Make sure that the light level is above 7, and that there is grass near the spawner.
The mob spawner cage's official item number is: 52
The ID for a mob spawner is 52. Type "/give (your name) 52" without the quotations and you should receive a mob spawner.
