The easiest to fold are the Happy Trails Pet Stroller, Happy Trails PLUS Pet Stroller, and the AT3 Pet Stroller. With each of these models, you simply slide one button with your thumb (the lock), depress the large button on the handle (the release), and then immediately and easily fold to 15″ to 18″ high.

Here’s a video showing the process of folding the AT3 All Terrain Pet Stroller.

The Walk ‘n Roll Pet Stroller is also easy to fold. It requires two hands, since the brackets on either side must be slipped upward to release the lock and fold the stroller to less than 10″ high. The Walk ‘n Roll is smaller than the Happy Trails, so the size of your pet and the amount of room your pet desires will affect which stroller you select.

Here’s a quick video showing the Walk n’ Roll Pet Stroller being folded.

The line of strollers from Kittywalk do not fold as easily as the other pet strollers. The stroller portion of the Kittywalk collapses flat, but the carrier portion can be collapsed only by removing a number of braces. While the other pet strollers collapse in seconds, the Kittywalk strollers require a couple minutes of effort to collapse and reassemble.

Don’t get me wrong, the Kittywalk pet strollers are still very recommendable–they are very sturdy, spacious, and functional. One benefit the Kittywalk has the others don’t is that the carrier portion is detachable. Other benefits include the variety of sizes, styles, and colors available, the fact the stroller portion can be used without the carrier to roll groceries or other light loads, and the privacy area that permits your pet some solitude while in the pet stroller.

This should give you a good idea of the folding abilities of different pet strollers. Just make sure you know what you need from a pet stroller before you buy. Do you need one that folds quickly and easily or do you need a detachable carrier? Answering this question for yourself will help you find the perfect pet stroller for you and your pet.
