Of course, Professor Slughorn belongs in Ravenclaw! Just look how smart he is; he's a brilliant potions teacher (maybe not *quite* as brilliant as Snape, but on the other hand he's not even half as grumpy as him), knows how to teach his students very well and also knows how to get them to understand what he's actually talking about. This requires great skill and feeling, and is a very eagle-like trait. But all in all, he knows very well how to present himself and what to do to get what he wants or at least open more doors for himself, which again requires a lot of cleverness! There is also this loveable strangeness he radiates a bit, that, again, is a very Ravenclaw-ish trait. He is definitely an eagle, in every way! Even though he has a small Hufflepuff side too, looking at how he cares about his students, but... No, definitely a Ravenclaw.
