Cats are notoriously fussy creatures. If you’ve ever tried to change their food, move their bed, or—heaven forbid—relocate their litter tray, you’ll know exactly what I mean. So, when switching your cat to a new litter type, it’s no surprise that things can get a little… complicated.

But don’t worry—you’re not alone in this. Whether you’re making the change for health reasons, environmental concerns, or simply because the current litter isn’t cutting it, this guide will help you navigate the process smoothly and successfully. We’ll cover everything from choosing the correct type of litter to recognising signs of stress and troubleshooting common issues.

Why Switching Cat Litter Needs Careful Planning

Let’s face it—cats are creatures of habit. If they’re used to one type of litter, suddenly introducing a new one can feel like you’ve swapped their favourite cosy blanket for sandpaper. This small change can trigger confusion, stress, or even full-blown litter box rejection.

So Why Change Cat Litter In The First Place?

You Might Be Switching Because:

  • Your current litter isn’t clumping properly or controlling odour
  • Your cat has developed allergies or respiratory issues
  • You’re looking for an eco-friendly or flushable alternative
  • You’ve adopted a new cat and need a multi-cat compatible option

Whatever the reason, change is fine—as long as it’s handled with care.

Choosing the Right Type of Cat Litter

Before making the switch, let’s discuss the types of litter available. Each has pros and cons, and not every cat will love every type. Understanding the options will help you pick one that aligns with your goals and your cat’s preferences.

Common Types of Cat Litter:

  1. Clay-Based (Clumping or Non-Clumping)
    • Popular and easy to clean
    • Not biodegradable and can be dusty
  2. Silica Gel Crystals
    • Great at odour control
    • Less tracking, but not biodegradable
  3. Natural Litters (Tofu, Corn, Wheat, Pine, Paper)
    • Environmentally friendly and often flushable
    • Can be more expensive and less absorbent
  4. Scented vs Unscented
    • Scented litters may smell pleasant to u, but can overwhelm your cat’s sensitive nose.

      Tip: According to the Humane Society, cats prefer unscented, fine-grain, clumping litter. But every cat is unique—some love the piney scent, while others loathe it.

How to Switch Your Cat to a New Litter Type: A Step-by-Step Process

Changing cat litter doesn’t need to be dramatic. Slow and steady wins the race here.

Step 1: Start with a Small Blend

For the first few days, mix 25% of the new litter with 75% of the old one. Keep everything else constant—the same box, the same location, and the same cleaning routine.

Personal Story: I started mixing it slowly when I switched my senior cat Luna from clay to recycled paper litter (because of her asthma). The first time she pawed at the new stuff, she gave me a look of sheer betrayal. But by day five? She didn’t bat an eye.

Step 2: Gradually Increase the New Litter

Over the next 7–10 days, increase the proportion:

  • Day 4–6: 50% old, 50% new
  • Day 7–9: 25% old, 75% new
  • Day 10+: 100% new litter

You can stretch this timeline if your cat seems hesitant—there’s no rush.

Step 3: Observe Behaviour Closely

During the transition, watch for signs of stress or litter box avoidance.

Some warning signs include:

  • Refusing to enter the litter box
  • Digging but not eliminating
  • Eliminating outside the box
  • Excessive grooming (a sign of anxiety)

If this happens, go back a step and give your cat more time. You might even want to offer two litter boxes temporarily—one with the old litter and one with the new.

Step 4: Keep It Clean

A pristine litter box makes change easier. No cat wants to deal with a smelly box, especially when it’s already unsure about what’s inside.

  • Scoop at least once a day.
  • Clean the entire tray weekly.
  • Use mild, unscented soap and warm water—nothing too strong or chemical-laden

What Can Go Wrong (And How to Fix It)

Even the best-laid plans can hit a bump. Here are some common hiccups—and what to do about them.

Problem 1: Cat Refuses to Use the New Litter

This is probably the most common issue.

Try:

  • Going back to a transition stage
  • Mixing even smaller amounts of the new litter
  • Placing a second tray with the new litter nearby

Problem 2: Multiple Cats, Multiple Preferences

Cats are like flatmates—they don’t always agree.

If you live in a multi-cat home:

  • Provide one litter tray per cat, plus one extra
  • Try switching one tray at a time
  • Observe which litter each cat prefers

Fun Fact: A 2020 study by the Journal of Feline Medicine and Surgery found that cats clearly preferred unscented clumping litter when given options.

Problem 3: New Litter is Dusty or Tracks Everywhere

Not all litters are made equal. If you’re dealing with paw prints across your floor:

  • Opt for a low-dust, low-tracking formula
  • Use a litter mat outside the tray
  • Trim the fur between your cat’s toes (yes, really)

Bonus Tips for a Pawsitive Transition

  • Try Feliway or calming sprays near the litter box
  • Reward your cat with treats after using the new litter
  • Avoid sudden changes to feeding, sleeping, or play routines during the switch
  • Don’t change the litter brand too often—consistency is comforting

Frequently Asked Questions

How Long Does It Take To Switch Cat Litter?

Most cats adjust within 7–14 days. Some may need longer, especially older or more anxious cats.

Can I Change The Litter Type Overnight?

Technically, yes—but it’s risky. Sudden changes can lead to litter box aversion. Always aim for a gradual transition unless medically advised.

My Cat Has Stopped Using The Litter Box—Help!

First, rule out medical issues like urinary tract infections. If health isn’t the cause, return to the litter they were comfortable with and try again more slowly.

Make The Change, But Make It Smooth

Switching your cat’s litter doesn’t need to be a source of stress for either of you. By taking a gradual, thoughtful approach, you’re far more likely to achieve success and avoid accidents on your living room carpet.

Here’s what to remember:

  • Choose a cat-friendly litter that suits your lifestyle
  • Introduce the new litter gradually, over 7–14 days
  • Watch for signs of stress and adjust your approach as needed
  • Keep the litter box spotless and inviting
  • Be patient and consistent—your cat will thank you (eventually)
