Sorry amity going to have to disagree with you there. Have you tried getting a Syrian in a large carrier with a hide and a nice amount of bedding? It's a nightmare. Also hamster can get flung regardless of carrier size.

I agree with Luna. You can put in enough bedding and a decent size hide. Cardboard box will act as a divider so can make the space smaller if needed. The hide is necessary as it creates a dark space for them to feel safe, thus less stressful.

When I took Niko to the vets he was in a carrier meant for rats/guinea pigs. Plenty of bedding and a hide or 2 later it fills the space quite a bit. Also whilst driving with many bumps in the road, a hamster isn't going to be flung about.
