Pestell Pet Products 683091 33 lb Pestell Life Mate Scoopable Cat Litter with pH Health Alert Bag

After using the product for a while, I contacted the manufacturer and they sent me high and low PH testers. There are small flakes added to the mixture that will turn bright red if hi PH liquid is introduced. The low PH indication didn't seem to work. Besides, there are blueish particulates in the litter that would confuse you anyway. My concern is High PH and for that, the product does work. The litter itself seems to be natural, effective, non-dusty and has no heavy perfumes which some cats don't like.Bottom line is that they need to:A) Add more of the active flakesB) Check why the low PH is not activatingC) Reword their pretty packaging to indicate that it's the "flakes" that will turn color and not the entire litterThe company has a good idea but needs to listen to customers and improve it.
