Pets before Cata

[Areon]

Ok, well I'm trying to grab 5 Rare pets before Cata comes out, or atleast 4.0. I've been messing around on the PTR this morning and thought about this. With BM Hunters with Core Hounds getting Bloodlust now (hehe) I find myself wanting pets that may not even be in Cata but still in Wrath. So right now I have the following:

Echeyakee - White Lion
Arcturis - Bear Spirit Beast
Soriid the Devourer - Purple Silithid
Bjarn - White Bear
Snarler - Black Wolf

Now the first 2, I'm keeping no matter what...but the other 3 well I'm willing to Change them, but at current I do need a wolf for raiding before Cata hits. So Any Ideas? I was thinking bout grabbing a red Core Hound since I seem to see the blue or green more on my server. And since I think MC might get removed or revamped it might be nice to have him.
