What I would look for in a carrier is one that can be completely enclosed and zipped up. Even thought they can be enclosed there is always a door or a zipper where they can peek out if you want. Also, I always find out how much the carrier weighs because my Teddi only weighs 3 lbs. so I don't want a carrier that is heavy (which is why I would never get one of those Juicy ones - they are so so heavy). That's my 2cents
