Amazon.com : OxGord Pet Stroller Cat Dog 3 Wheel...
Very reasonably priced! Was easy to assemble-just put the wheels and the front foot rest on. The only problem I had with the assembly was that Huey grabbed one of the little plastic "hubcaps" and chewed it all wonky before I could put it on the wheel. I was able to straighten it out & make it fit, though. The stroller seems to be quite sturdy, too. Huey has a basket-type car seat that he loves, so this isn't much different from that to him.
