Petique's Simplicity Pet Stroller is extremely light and durable for you to push. The small, yet heavy duty wheels on the Simplicity are designed to stabilize the entire stroller, giving your pets a smooth ride and providing you a nice, relaxing walk. A spacious interior was designed to reduce stress and anxiety. The large ventilated mesh windows on the canopy gives your pets the proper air flow they need to enjoy the ride and the all-around great view of the outside world!
