Not good for outdoors. We put this together and immediately saw large holes in the bottom where the pieces don’t fit snuggly. My husband commented that mice could get in the holes. Sure enough, 5 days later mice had gotten in and chewed a pillow. We live near a wooded area so this might not be a problem for everyone. He put spray foam in the corners but there are also huge gaps where the lid connects to the back. We will see if the mice get in that way. There is no way to fill those gaps because it will affect the lid opening and closing. I would not recommend this to use outside.
