I have been using the Neutralize It! product for a few months now. I used it in my brooder house with my chickens and it immediately starts helping with the smell that they put off, plus they love pecking at it for the extra calcium in their diet. It also helped keep all the moisture contained in the brooder. I also tried it out in our dog kennels and made a huge difference. Now, I put it down every week after I clean out my chicken coop and our dog kennels.  I will definitely be buying this product in bulk and testing it out with the rest of our animals.
