I built this for my cats. There is a 120mm computer fan and a motion detector set to run the fan for 5-minutes when the cat enters the box. Kitties shouldn't have to take a #2 without fresh air, should they?
"I had my double glazed window changed last month (water damage), but it wasn't installed right. Only 3 days later, a huge crack appeared. I immediately called the company that installed the window and they told me nothing could happen. But a new window will be installed soon. I don't trust huge cracks in my windows so duct tape to the rescue! I think it's kinda artsy!"
It DOES have a sort of abstract art quality to it. Keep it if you don't mind sacrificing the view!
