TrustyPup Haustiertransportbox, klein

Took this on a three-hour drive and my cat actually stayed calm the whole way, which never happens. The carrier feels secure enough that I'm not worried about her pushing her way out, and it's easy to carry with one hand while juggling the rest of my stuff.

Fits my 9 lb terrier mix with room to spare, and the whole thing stays balanced on my shoulder even when he shifts around. The zippers glide smooth, which matters when he's squirming to get out at the vet.

My cat actually settled down and napped within five minutes of being inside, which has never happened with any other carrier we've tried. The small size fits perfectly under the airplane seat in front of me, and the whole thing feels sturdy enough to last through years of vet trips.
