As we all know, kidney disease is one of the most common chronic diseases in cats. The pH value of healthy cat urine should be maintained between PH 6 and 6.5 .
 
The DooDoo Buster Detector Cat litter will change colour to red if the urine has higher acidity, so you can take the first step to change the cat’s diet to prevent further problems! 
 
One set of DooDoo Buster litter comes with 2 Destoyer and 1 Detector. Detector is used every 3 to 4 weeks to check on the cat’s urine acid level.
