My rabbit may well stink, if you let them. The mats reliably prevent next to the toilet gone transformed directly into a toilet aroma. I use the mats cut into the Kloecke, and in my multi-storey cage on the upper floors, where rausgescharrte litter makes just dirt. As the animals defecate only at the bottom and let the water, they hold up for months, as long as the play instinct permits. In the Kloecke I trade them only about a month (the bedding changed about course regularly, just like the toilet sand), I will cut a mat in three pieces and put the pieces only one alternately. The cutter goes quite smoothly, and my animals have it clean and I odorless.
