Switching your cat to a new litter might seem simple, but for your feline friend, it can be a big adjustment. Cats are creatures of habit, and even a small change to their litter box can feel like a disruption to their routine.

Whether you’re moving from clay to a plant-based litter or just trying something new, the key is to go slow, stay consistent, and make the change feel as natural as possible.

Why cats resist change

Cats rely on scent and texture to feel safe. Their litter box is part of their territory, and changing its smell or feel can make them uncertain.

The most common reasons cats resist new litter include:

• Different texture: Some cats prefer fine grains, while others like larger pellets.

• New scent: Strongly scented litters can be off-putting, especially for sensitive cats.

• Change in environment: Moving the litter box or altering too many factors at once can cause stress.

Understanding why your cat might hesitate helps you plan a smooth, stress-free transition.

Step 1: Start slow and mix gradually

The best way to introduce a new litter is to mix it with your cat’s current brand. This lets them get used to the new texture and scent gradually, without feeling like their safe space has changed overnight.

Start by mixing in about 25% of our litter with your current brand. Every few days, increase the amount until you’ve fully switched. Most cats adjust within two to three weeks, but if your cat seems nervous or avoids the box, slow the process down.

The American Association of Feline Practitioners (AAFP) and the International Society of Feline Medicine (ISFM) recommend transitioning litter over six days. However, some cats may take a little longer — especially older or more anxious ones.

If you are replacing your litter setup as well, it’s a good time to review your box hygiene routine. You can check out our guide on 4 tips for a stink-free litter box for simple daily cleaning habits that make every litter change easier.

Step 2: Keep the box in the same place

Try not to move the litter box or change multiple things at once. A consistent location helps your cat feel safe during the transition. If you move the box to a new spot while also changing the litter, your cat might get confused and avoid using it altogether.

Keep everything else the same — same box, same area, same routine — until your cat is fully comfortable with the new litter.

Step 3: Use familiar cues

Cats find comfort in familiarity. You can help your cat accept the new litter faster by sprinkling a small amount of their used litter on top of the new one. The familiar scent reassures them that this is still “their” space.

Avoid using strong detergents or air fresheners when cleaning during the transition. Cats prefer a neutral smell and may avoid a box that smells too unfamiliar.

Step 4: Observe and reassure

Keep an eye on your cat’s behaviour throughout the process. If they start hesitating, scratching around the box instead of using it, or eliminating elsewhere, it’s a sign that you may be moving too quickly.

Go back a step in your mixing ratio and give your cat more time. Stay calm and encouraging, and always reward positive behaviour. Cats respond best to quiet consistency.

Troubleshooting litter problems

Sometimes, despite your best efforts, things don’t go according to plan. If your cat suddenly stops using the litter box or seems uncomfortable, there could be several reasons:

• They may dislike the texture or scent of the new litter.

• The location of the box may be too noisy, too enclosed, or lacking privacy.

• Some cats dislike covered litter boxes because odours get trapped inside.

If you’ve adjusted these factors and your cat is still struggling, it’s worth consulting your vet. Sudden changes in litter box habits can indicate health issues such as urinary tract infections (UTIs) or discomfort, especially in senior cats.

A vet check ensures your cat isn’t experiencing any underlying problems and helps you rule out medical causes before making further adjustments.

The takeaway

Transitioning your cat to a new litter takes patience, observation, and consistency. Mix slowly, maintain a familiar setup, and give your cat time to adapt.

With a gentle approach and a clean environment, your cat will soon adjust — and you’ll both enjoy a fresher, more sustainable litter box routine that works beautifully for your home.
