I know this is a bit of a late post, but I just had to respond!
This is such a great idea! I love it!
I decided to take the quiz that is also on that same page; the quiz that sorts your pup. I did it for both my dogs and they both got Hufflepuff!
EDIT - I also took the quiz for my cat just to try it out, even though I know the quiz is for dogs. She got Ravenclaw, which might not be totally accurate as the quiz was for dogs, but whatever. I would also say that she would be good in Ravenclaw. And if my kitty really is a Ravenclaw, then we are both in the same house (I'm a proud Ravenclaw, too, lol).
