Review on Ultra Cat Health Monthly 🐱 Monitor Crystal: Ensuring Optimal Feline Wellness, 16oz by Jessica Redmann

I used the litter exactly as directed - sprinkled on a clean tray of fresh litter. I have 2 older cats who have been neutered and thought this was the perfect way to test their pH levels. One of them refused to use the tray at all and went about his business (for the first time in his life) in the corridor across the house. Another cat buries everything so carefully that you can't see if the color of the stuffing has changed. Don't waste your money on this product.
