Also, another suggestion I could offer would have to be Drakah's World of Warcraft UI-emulating mod. Personally, I don't use it for my pet classes (I've become too attached to the UI I use, I suppose), but it is very clean and efficient (as WoW's UI is), and though the pet window doesn't stand out like a big black dot over a white background from a burned out pixel in your monitor, it is noticeable enough, and relays all the information you'll need readily at hand.

Hopefully this will help you out in your search. Another option I could see would be to check the various "evil" themed UIs under the Complete UI section...there's a few rather striking ones, there.
