I originally bought the Go Pet Club Pet Stroller because 7 years ago I adopted a sibling pair of rescue cats, brother and sister. In the apartment building I live in over a number of years we had had several evacuations. When they were little I could have evacuated them if need be in one carrier( the would have been crowded). I knew as they got bigger I could not carry two carriers down flights of stairs that are narrow and only there for evacuations. That is when I bought the Pet Stroller. Thankfully I have never needed for an evacuation. I have used it a few times when I have taken either of the cats to the vet when going with someone with a SUV or CRV. Otherwise it was just sitting around gathering dust, so finally one day I set it up in my "living room" ( my bedroom,the only other real room in my apartment is to small) while I was doing things. They took turns hopping in it and would fall asleep in it. Both of the cats vie with each other to see who can get there first. I'll leave it up for a few days when they stop being as enthusiastic I take it down and leave it down for several months. They have a " new toy" or " cat furniture" and I know if I ever need to use it to evacuate they are not afraid and in fact love it.
The stroller has storage underneath as well as something to clip onto the handles with a place for soda, keys etc. I found it easy to unfold. The collapsing was a little trickier for me because I couldn't quite figure the diagram out. Once I knew how to do it I have had no problems since. I would highly recommend this.
