Well, the medium snoozer arrived!
And it is BIG...much bigger than her other car seat. Right now I have it in the living room and she'll use it as a bed (somewhat ironic, because I bought her a Snoozer Cozy Cave bed for Christmas and she won't go near that thing
). At least she has plenty of room to lie down in it. I think it will be great for long car trips as well as for when my Mum or Dad pick her up.
I still prefer the Pet Gear car seat for regular use around town though. The sides of it are firmer, so ZoE can stand up with her paws on the sides and see out the windows better.
