What's the meaning of じゃねーよ and じゃねえん?


I'm actually getting a little confused about these words' meaning,

The original sentence is:

> 生まれちゃった☆ じゃねーよ! ハムスターじゃねえんだぞ!

Does じゃねーよ mean "Not....., you know?" Something like that?

Is it a colloquial form of じゃない?

Is じゃねえん also a colloquial form? Does it mean too bad?




ねー and ねえ are both corrupted ない ([ai-to-ee
contraction](https://japanese.stackexchange.com/q/18454/5010)). よ and ぞ are
sentence-final particles (ぞ sounds relatively stronger). んだ is short of のだ,
where this の is an explanatory- _no_ , which in this case is used to convince
the listener.

  * じゃねーよ = じゃないよ = ではない + よ
  * じゃねえんだぞ = じゃないんだぞ = ではない + の + だ + ぞ

Thus a very literal translation would be:

> Not "[happened to be] born!" [It] is not a hamster!

The first Xじゃねーよ is a common pattern of _tsukkomi_ used after repeating
someone's silly statement. It's like "How dare you say X?", "X? Seriously?" or
simply "Ha! X!".
