I was so fortunate to find Perfect Litter Alert product for my cat. You know the name says everything...PERFECT! I've tried other litters that are natural but, never have I found a product that is eco-friendly, clumping, great odor control and best of all it lets me know if my cat has a Urinary Tract Infection. I love my pet so I'm willing to provide only the best product for her. I highly recommend this product to anyone that has feline furry pets. You know the litter box can be a night mare if you don't have the Perfect Litter. I'll never change litter again.
