I found this tonight. I like the idea of it having a shoulder strap and fits on the front seat. My girl will prob like this one much better than her other carrier, not like she ever used it! She travels with me lots. Just thought some of you might be interested.
Oh its on sale here though...

Those types of bags are great, I definitely think the cats like them better than those hard plastic ones. One thing to keep in mind if you fly...that particular bag is not one that you can put under the seat in front of you. I have the medium size Sherpa bag SHOWN HERE It's more expensive, but it is airline approved, should that be a need for you and your girl.
