When I first received the box I was a bit surprised at how heavy it was. Obviously the actual litter box is not very heavy at all. It was super easy to set up and was done within minutes. It was large enough for my big cat to go into which was awesome. I think even after using it outdoor you could bring it indoor and continue using it. Even taking out the litter and just using it as a little "home" for your cat would work well. I have an adopted cat that was a stray who enjoys being outside. He actually needs to be outside at times and will go a little bonkers if you don't let him out. I actually just sit this outside for him to run into whenever he feels like it. I think a more durable weatherproof material would be awesome for those who care for strays. Overall I am really happy with the quality of this product. I think it would benefit many different people and would be great to donate to animal care centers and shelters. [This review was collected as part of a promotion.]
