I’ve noticed that when my cat paws through her catbox it raises a lot of dust. I run an air filter near it but I don’t want/need to run it all day or turn it on by hand every time she uses the catbox.
Its the Internets to the rescue! This gentleman blogged about a motion-sensor outlet, which turns any appliance into a motion-activated one. Now I can hook the air filter up and only have run it when the cat’s near the catbox.
Problem solved. Thanks for the tip, Joe!
