What to put inside a litter box?

Most cats prefer unscented, clumping litter with a sandy texture, filled to a depth of about 2 inches; avoid liners, scents, and noisy materials.

What to Put Inside a Litter Box: A Complete Guide

Keeping your cat's litter box comfortable and clean is essential to promoting healthy elimination habits and avoiding stress-related behaviors. While preferences can differ from one cat to another, there are universal best practices when choosing what to put inside a litter box. This guide will walk you through the essential components.

1. Choosing the Right Type of Litter

Clumping Litter: Most cats prefer clumping, unscented litter. It mimics a sandy texture, which appeals to their natural digging instincts and helps with easy removal of waste. Non-Clumping Litter: This alternative may be needed for certain health conditions or preferences, but it requires more frequent full changes. Alternative Litters: Plant-based, silica, or recycled paper options are good alternatives for eco-conscious households or cats sensitive to dust. Scented vs. Unscented: Always choose unscented litter. Cats have highly sensitive noses, and fragrances may deter them.
  • Fine-grain texture is most accepted by cats.
  • Low-dust varieties can reduce respiratory irritation.
  • Choose a brand your cat consistently uses without complaints.

2. How Much Litter to Use

A general guideline is to maintain a litter depth of about 2 inches. This depth allows enough room for digging and covering waste without being too deep, which can bother long-haired cats or make movement difficult.
  • If your cat is frequently scraping the bottom, add a bit more litter.
  • If your cat avoids stepping in, it may be too deep—adjust accordingly.

3. Litter Box Liners: Yes or No?

Liners are generally discouraged. They tend to catch on claws, cause irritation, and may discourage use. Instead, wash the box regularly with mild soap for hygiene.

4. Mats and Accessories

Place a litter-catching mat or soft rug directly outside the box’s entrance. These help reduce litter tracking and protect your floors. Avoid crinkly or noisy materials, as cats may find them unpleasant.

5. Litter Box Shape and Size

While not technically “inside” the litter box, the box's size impacts usability:
  • It should be at least 1.5x the length of your cat.
  • High sides are good for preventing spills, but may be tough for older or disabled cats.
  • Open-top boxes are often preferred over covered ones due to better ventilation and visibility.

6. Cleaning Frequency

Maintaining a clean box is just as important as the litter type:
  • Scoop daily to remove waste.
  • Replace litter every 2–3 weeks for clumping types if scooped daily.
  • Clean the box with mild, unscented soap during litter changes.

7. Location Tips

Where you place the litter box matters immensely:
  • Quiet, low-traffic areas work best.
  • Keep it away from food and water bowls.
  • Ensure the cat has clear escape routes and isn’t cornered while using the box.
  • Spread boxes across floors in a multi-story home.

8. When Introducing New Litter

Cats are creatures of habit. When changing to a new litter type:
  • Gradually mix new litter with old to ease the transition.
  • Observe for any signs of avoidance.
  • Do not punish accidents—instead troubleshoot box placement or medical concerns.

9. Special Considerations

Certain accessories or setups may suit specific needs:
  • For dogs in the home, use covered boxes inside cabinets with cat-only access.
  • Use baby gates to restrict access in shared homes.
  • Consider large storage containers for larger cats.
  • Add odor control accessories—but never as a substitute for cleaning.

Conclusion

When deciding what to put inside a litter box, keep your cat’s comfort and instincts in mind. Aim for unscented, clumping litter with a sandy feel, maintain shallow but sufficient depth, and skip liners or fragrances. With regular cleaning and thoughtful placement, your cat will have a secure, hygienic bathroom spot they’re happy to use.
