I ordered Boxie cat because all we smell is the litter box no matter what litter I buy. My cat is super picky and if the box smells at all he will not use it. So I clean it out all the time. With Boxie cat we have NO smell at all. The cat hasn't gone any where in the house since we switched. I love that it comes every month and it works out to be less money since I am only replacing the whole box once a month. THANKS BOXIE CAT!!
