I have the Lookout.. larger size. Shelby & Seymour LOVE it. They can both lay down in it. ( It holds up to 18 Lbs) They are more on the "Teapot" side .... haven't weighed them for awhile, but around 8 lbs ea. ( yes, Shelby is still dieting!!

)
Shelby used to get a little nervous at first when she went for a ride.... now we don't notice her getting nervous at all!
I got mine from the Snoozer bed website ( I think that they advertise on YT).
