The frequency of changing cat litter depends on several factors including the number of cats, the type of litter used, and your cat's habits. Here are the general guidelines:

• Scoop waste daily: Remove clumps and feces at least once a day to keep the litter box clean and odor-free

• Full litter change:
  • For one cat using clumping litter , change all the litter every 2 to 4 weeks

* For **one cat using non-clumping litter** , change it about once a week

* For **multiple cats** , litter needs to be changed more frequently-possibly several times a week or even daily if many cats share the same box

• Cleaning the litter box: When changing litter, wash the box with mild, unscented detergent and avoid harsh chemicals like ammonia or bleach, as cats are sensitive to smells

• Adjust based on your cat: If your cat seems unhappy or avoids the litter box, or if you notice odor or litter breaking down, increase the frequency of changing the litter

• Additional tips:
  • Maintain 2-3 inches of litter for non-clumping and 3-4 inches for clumping litter to allow digging

* Provide one litter box per cat plus one extra to reduce litter box issues and litter changing frequency

In summary, scoop daily and change the entire litter every 1 to 4 weeks depending on litter type and number of cats, with more frequent changes needed for multiple cats or non-clumping litter
