I've got around 20 of the Cabin Kennels for my rescue. I've used so many of the other kinds and this is definitely my favorite. I really like the wire top too for being able to see in easily and add some treats. I transport a lot of piggies who board with me and many of them are in the Kaytee carriers above. I have to put towels under those so they won't get my car seats wet.
My only complaint about the Cabin Kennels is that they aren't easy for hanging a water bottle on them. You can tape one on, or just bring lots of water-loaded veggies such as cucumber and lettuce along.
