I have 3 other carriers and this is the best carrier I have purchased. I have 2 rabbits that fit perfectly in this carrier. I spent weeks researching about carriers and I am so glad I ordered this one. I really like the 360 view because I am able to see my rabbits and it also gives them good ventilation. The bottom is sturdy so they have a flat surface to sit because honestly they don't really enjoy car rides but this carrier is the least stressful for them to transport. The top can be opened from both sides by a simple push of a button. I wish I had bought it with the stroller because I don't think they sell just the stroller part separately. Also the fact that I can collapse the whole thing to save space is a major plus. I love it and would buy it again!
