Alright listen up, buttercup. The joke is all about wordplay, see? A "meowtain" sounds like "mountain," because cats meow. And a "cheese grater" is something you use to grate cheese, but it also sounds like "great," so it's funny because it's unexpected. It's not that funny though, since you are reading this explanation, you are obviously a dummy.
