We have two cats and have found that odors from the litter box comes due to dried urine stuck to the litter box's bottom and sides. It is best to empty the litter all out of the box once a week and wash out the box with bleach and rinse very well if a liner is not used. This will kill bacteria and the odors. We use the clumping litter and works very well when we use the litter box liners. We simply scoop out the clumps twice a day and put in fresh litter in after we put in a fresh liner. Janice

I have never owned cats so do not know much about them. I am babysitting our son's cats this week. Their litter box stinks to high heavens. He uses clumping "the World's Best Kitty Litter". I thought if I empty out all of the litter and wash the boxes and start with all fresh litter it might help? Does anyone have suggestions in what to do that won't make them not use their box? He feeds them Evo. Could their food be making their poo really smelly? They are very healthy looking and their bodies do not smell, just the box. Ew, Sue MI
