Do you travel with you pet? I travel with Lexi quite a bit. I used to travel with her in one of those small plastic rectangular crates with vents in it. It is really hard to hold that when you are trying to travel with your carry on luggage , your pet along, food for her & with your purse.
She goes with me in her Celltei Backpak-o-Pet. Take a look.....
