Picture of motion activated cat litter box odour fan

This is a simple set up for a stinky problem.  (it works better then it looks, i just quickly set it up to see if it works) 
the motion switch I used turns on for 5 minutes but can be set for 10 or 30.

I used the following:

1 cardboard box big enough for the litter box and for the cats to move in
1 small hair drier (2 dollars from a second hand store, you can use a vacuum but it make a lot more noise)
1 motion activated power switch (35 dollars)
duct tape
small extension cord
laundry drier sheet
rubber band

Step 1: Hair drier set up

use a hair drier with a cool setting, tape down button for the cool setting and switch on low
fold laundry drier sheet and cover the end that blows, use rubber band to hold in place.

plug in to see if the hair drier is working on cool and air is flowing through the drier sheet

(i had to remove the hair drier handle so it would fit better)

Step 2: The cardboard box

cut a hole in the front of the box for an entrance and make sure the top of the box can still trap the stink. (if you cut the entrance all the way to the top of the box, the stink will escape at that location)

I also made the entrance big enough for the litter box to slide in and out, for an easy cleaning.

cut two small holes in the top.
one hole is for the hair drier intake and size accordingly
the other is for the motion senor and size accordingly
