Review on Nature's Miracle Premium Clumping Corn Cob Litter: Odor-Banishing Bio-Enzymes, Dust-Free Excellence by Valerie Petty

This is a very expensive choice. The filler smells after each use, so you will have to invest in another product that will help eliminate the smell - this is an additional cost. Also because of that you have to change it quite often, I throw it out every 5 days just because it smells bad and doesn't stick very well. My cat loves it and won't want any other, so that's my 3 stars. I've tried switching it to a different brand a couple of times but she wouldn't use a different brand. If you've just adopted a cat, try bringing something else with you while she gets used to it.
