Fast Eddie - yes, Schatzie can lay down, sit up, or turn around without getting any sort of tanglement by her attachement to the carseat, it is wonderful.
Avborges - almost all pet supply stores carry them. I will do some research again to find out where I got Schatzie's. It was only like $20.00 Not a bad price to keep them safe huh? It has pouches on both side ends (mesh bags) and a front zipper pouch to hold goodies (treats) and or what not.
I had it when we had Half-Pint who was only a little over a pound. I purchased a small kids pillow to place in the seat to lift her up a bit cuz she was too small for it. (imagine that) However, Schatzie fit's perfect and she is a little over 7 pounds.
Again, I will get back to you on the web site where I found the seat at.
