After a LOT of research, I bought this pet carrier to help me get out with Chester, my cat. (I am disabled and need to be able to push or drag his carrier along, because picking him up is not an option for me.) I've used it twice for a trip to the vet. It has a 4.5 (out of 5) star rating on Amazon.ca, is really very well made and sturdy. The cabin of similar ones that I looked at, easily fell off their wheels! NOT this one! For me, it's just a bit awkward and far too large for my 1 cat. It's best suited for a pair of something or a medium to larger sized dog.
