Gen7Pets strollers are the only ones I would ever consider! I had purchased another brand from a pet store & my cat escaped within 2 minutes so I returned it. Thank goodness we were still inside! Originally I bought it so I could walk to the vets. My cat weighs 12 lbs & very long. He fits comfortably. This stroller is made well & completely secure! It also has a great cup holder for me & a large zippered basket below so you can bring everything you need. My cat absolutely loves it & it's also  his favorite place for naps! 

Pros: extremely secure, great price although I would gladly pay more, easy to push & maneuver
Cons: None
