Oh, this is great! I actually use someone else's mod for this same thing but since you uploaded this here I don't have to go looking for an updated version of that one when I install Pets! :MrGreen:
You may not have noticed the post icons but there are icons for the various expansion packs to show people right away which expansion pack a mod was made with. I edited your post to include the post icon. :) There are also "smilies" for the various expansion packs.
