This box is ideal for travel, meant for transporting small pets (smaller than a hedgehog) or insects. Measures approx. 11.5 inches long, 7.5 inches wide and 6 inches high. This box has not been used and nothing has been put inside it. I assembled it and had planned to use it for my hedgehog but the opening at the top is too small for a hedgehog. Flip top cover design, easy to feed, water, clean up. Cover lid has two locking latches at the top to prevent climbing escape, more secure! It has lots of small air hole slots.
