Does anyone have a suggestion on what is the best kitty litter to use to control oder. It is not necessarily his elimination that stinks so much as I keep it cleaned out, but the litter seems to have a horrible oder after a couple of days. I have used baking soda in it and that hasn't helped. My previous kitty wouldn't use an in door potty and always went outside. I just wonder if I notice it more. It does give me a headache. There is no other place to place his potty. Hope someone can help.
