We know that odor control is a pet parent’s #1 concern when it comes to choosing a litter. That’s why we’ve taken our naturally powerful odor-controlling litter and enhanced it with triple-action enzymes to neutralize fecal, urine and ammonia odors upon contact. We call it Ultra Odor Control, and it’s the natural solution pet parents demand and our most powerful litter to date. Because BLUE Naturally Fresh is so absorbent, one bag of BLUE is equal to three bags of the leading clay litter. Hard clumps make cleanup simple and mess-free without having to scrape the box. Unlike clay litter which often throws off silica dust, BLUE Naturally Fresh is virtually dust-free so you and your cat can breathe easier! And BLUE Naturally Fresh doesn’t stick to your cat’s paws so it’s not tracked throughout the house.
