Easy Litterbox Odor Removal
If you have a cat, chances are pretty good that you have a litterbox. Keeping it clean and smelling fresh are always a problem. If you only have one or two cats, use the scoopable litter. It's easy to clean up and cost effective for just a few. If you have more cats then you should use the standard clay litter. Get a hooded litterbox if you can.
Forget about buying the filters. They are expensive and chances are the cats are going to end up somehow pulling them into the litterbox. I use dryer sheets. I cut one in half and slide each half into the top of the box where the filters would go. It cuts down on the odors, makes the room smell great, and is very inexpensive. If you start to smell the box, just pop in a new dryer sheet. Type and scent does not matter. Choose what you like and enjoy your home again.
