We have a snoozer lookout. Maggie loves it. She can put her feet up on the front or sides to stand and lookout. The sides bend just a little but it's ok and she generally puts here feet on the window ledge.
Maggie is pushing 11 pounds (hates to walk in the summer and I think she's gained!). When she was little we had one of those seats that hangs from the headrest. It was either this Outward Hound
http://www.petsmart.com/product/inde...AvailInUS%2FNo or one very similar. The straps were attached near the front of the seat. She used to love to go in the car, but always seemed nervous in the seat. I finally figured out that it just didn't feel stable to her. I think the bottom maybe had too much give and no stability, and when she would stand with her feet on the front the whole front would sag down. I got the snoozer and she loved it.
Now I need a seat that is portable enough to travel in my suitcase on a plane. We are using Spirit airlines, so it's a big charge to carry her Snoozer onboard. I thought of getting the Solvit Tagalong or something like it, but I wonder if they are any better than the Outward hounds that she didn't like.
I wanted to try the solvit on-seat version, but the company advised me that it is hard to dis-assemble once put together, and it sounded bulky even dis-assembled.
Thanks for any input on a hanging (foldable) seat that is also stable.
