Cat and I both really love this. She jumps in and sits patiently, waiting for me to push her around inside the house. She is still getting used to outside walks, but once we are on a quiet path, she seems to enjoy it. I think this is the most attractive and thoughtfully designed Pet Gear stroller. It was obviously designed with great care, with flaps covering metal bars. I didn't want to spend an extra $100 for air tires and kinda miss that, but the tires on this are soft enough. Plus this model just looks the best. There is a removable plastic liner that has a removable cover, but I think it is not necessary in our case because kitty does not soil inside the stroller. The stroller is probably a bit more comfy without the liner. I'm thinking of getting the extra plush soft liner that Pet Gear sells but it's too expensive. So I put a small pet blanket inside instead, though even that's not necessary. My only complaint is that the instructions for attaching the wheels (the only assembly needed) were unclear because the diagrams were very poor quality and maybe not even specific or accurate for this model (too hard to tell, the drawings were so bad). It was very easy once I figured it out but they should make clearer instructions so the orientation of the attachment is obvious. Also, the plastic smell bothered me indoors, but not cat, who happily jumps in for a nap. It should eventually air out and go away, like with many new things.
