This car containment/pet carrier is well made. There is a small strap with catch to attach to your pet's collar. The long strap is to be placed around the headrest. The seatbelt goes through a firmly sewn attached wide strap in the back. My 12 lb dog doesn't mind riding in it. The cushion is ridged cardboard faux sheepskin,so I place a towel which can be removed easily and laundered. Your pet is possibly half an inch higher. I repeat. This is NOT a booster seat. I hope it will prevent injury during a short stop or accident. I appears very well made.
I would use a carrier for each pet. They need to have room to turn around. I got one for my cat George. George is a bigger older cat; he is 15 lbs and he has gotten into it and a large is a comfortable size for him. I like for the way it is put together and will take wear and tear.:)
This carrier is very good looking with lots of mesh for an open feel for the pet. The concept is really well thought out. But.... the first time I took my 5 lb chihuahua in the car in the carrier, he pushed against the mesh and it separated from the zipper. Had I not been right there he would have pushed the rest of the way through and freed himself from the carrier. I'm glad I was not in an airplane when it happened. I really liked the carrier and it's too bad this happened, I returned it for a refund.
