You can use this BabyDan Pet Square pet pen to create a safe area for your four-legged friend. The pet pen is a flexible system that you can extend indefinitely with both small and large sections so it fits your home and needs. You can purchase the sections separately. If you don’t need the pet pen anymore, you can convert it to a pet gate by purchasing a wall attachment kit. You can use around a wide or irregular fireplace, doorway, staircase or as a room divider.
