"rats" should be aliased to "rat"

rats is just an unnecessary plural tag of rat and it isn’t even on the species list.

But what if it’s the exclamation, as in someone saying “Rats”?

@Blissful690
10 years of the site and nobody’s decided to use the tag that way (or, from what I can tell, to tag that expression with some other tag, either). If you think it should, please go ahead and get started.

Done.
