I have been using the clumping litter and no matter how many times I scoop or change the box, I get major litter box stink issues. yuck!!! I even got a covered box to see if it would calm the stench somewhat but has nothing. I have tried many different brands as well and still the same story. I have also tried non clumping, corn and the news paper type but did not like any of them. I'd love for everyone to help me out I would like to know what your favorite litteris and why?
