Using Tidy Care Alert is a piece of cake. First, pour the 3.63 kg of litter into your cat's litter box. Then, let your cat use it as normal. Each day, check the colour of the crystals. If they change, it might mean your cat's urine pH is out of the normal range, and you should consult your vet. To keep the litter working well, simply remove the solid waste and stir the litter around. This helps with absorption and odour control. Store the litter in a dry place to keep it in good condition. Don't let it get wet, as that can affect the performance of the crystals. Also, make sure to keep it out of reach of small children and other pets who might accidentally ingest it.
