め used as a suffix

[David Hallgren]

I'm currently reading a book called セロ弾きのゴーシュ by 宮沢賢治. It's about a boy that has trouble playing his cello but animals starts to visit him at night and helps him to improve. In the beginning he is quite rude and shouts at the animals that come but he gradually becomes nicer. In the beginning he seems to use め as a suffix, I haven't seen this before and don't know what it means. Any help would be appreciated.
例:
猫め。
鳥め。

it's kinda like yarou やろう。 that is, it's a bit rude or cheeky, could be translated as bastard, or rascal, or scandral, etc. (or not translated at all)
note やろうめ is also ok.

In a casual situation with friends it's a bit rude/a bit funny, in like a work situation or something it could be really shockingly rude - if you used it in real annoyance, or if you are trying to be funny and they don't get it.

Thanks for the info! I'm going away for a few days so I'll do this right now:

Merry Christmas everyone! Thanks for making my first year of learning Japanese a lot easier.
