This might be a silly question but anyway...Is there any way that is not gross and difficult? Trying to transition from regular litter to the breeze system was not fun, but maybe I’m doing something wrong. I guess to slowly transition I can put litter in the bottom part and the litter would catch the urine instead of the wee wee pad, but I don’t know if that’s be efficient..Any suggestions to make it easy? I live in a small apartment in nyc where the cleaning option is limited to the bathroom/tub. And I want to transition to Yesterday’s News if that matters.
