I’m in college right now and my parents live across the country. I like to bring my cat with me when I go home for the breaks and this was great. I got into a car accident in July, and I still have neck/shoulder pain, so to be able to roll around my cat was a life saver. PROS: - The base with the wheels is easy to detach and put away. - Also easy to put the base back on whenever I was waiting to get off the plane. - Very comfortable for my cat! During our layovers, I would unzip and expand the carrier. She loved it and it gave her more room to stretch when we weren’t on the plane. CONS: - Mine came with no shoulder strap. - Also came without an inner leash. I had to attach her seatbelt leash from my car onto one of the buckles where the shoulder strap would be. - This thing will roll away from you if you aren’t paying attention! There were times she was rolling to the side of me because I was walking fast to my next gate. Once I paid attention, it wasn’t that big of a deal for me. I love this carrier and so did my cat. She seemed less anxious on our trip, and she was comfortable in the carrier. I wish there was a shoulder strap, because I usually wrap the shoulder strap around my headrest when we go on roadtrips. I also was hoping for an inner leash since it makes me feel more comfortable knowing that she’s strapped in, but my seatbelt leash did the trick while we were traveling. UPDATE: We ended up roadtripping across the country with my cat. Not having the shoulder strap was hard since I couldn’t wrap it around the headrest to keep her secure. Also, not having the inner leash was miserable because she would jump out of the carrier and try to explore the car. Other than those two complaints, the carrier is great!
