Goal of the project: A tutorial on how to modify and build a relatively cheap ventilated cat box using cheap household products.
Once finished this post will link to the projects page. I have started a DIY project to pull a slight negative pressure inside the litter box and push air outside. The concept is exactly the same as installing a blower fan in your bathroom. Once working properly the kitty box should be nearly odorless.
Window Venting Cat Box
The cat box will be modified to vent outside using an existing window, and parts can easily be obtained on amazon or at a local hardware store. Full Details of the parts will be at the bottom of the full post.
Quick Clean Ventilated Cat Box
As part of this build we will modify a quick clean cat box the “Omega Paw Self-Cleaning Litter Box.” The plan is to take a proven product and hopefully make it better.
Cat/Litter Box Fan
The fan we are using is a USB powered fan that you can buy off ebay. For those of you who are concerned with power draw. The max possible electrical draw should be around 12.5 watts, but I expect to it take a bit less that that so it shouldn’t draw any more than leaving a small CFL light bulb on. (Note it will depend on the efficiency of the USB power source. If you use a bad one you could probably almost double the draw)
Expected Total Cost for Ventilated Litter Box
I’m expecting the total cost of the ventilated litter box to be around $50

$10 Powered PC fan (AC Infinity AI-MPF80A Quiet 80mm USB Fan for Receiver DVR Playstation Xbox Computer Cabinet Cooling)
