The key to switch cat litter is to do it gradually and step by step, adapting to your cat’s sensitive habits when it comes to smell and texture. This minimizes issues like cat litter box avoidance, inappropriate elimination, and stress. It also means keeping the litter box clean and using the right depth of litter. This method works for switching between all types of cat litter, such as mineral litter, tofu litter, and bentonite litter.
Step-by-Step Guide to Switching Cat Litter
Stage 1 (Days 1-2): Old litter as the main base, add a small amount of new litter
Leave 80% old litter in the box and mix in 20% new litter thoroughly, keeping the litter depth at 5 to 8 centimeters. Don’t move the litter box or change its surrounding environment. After scooping out soiled clumps each day, top up the litter following the 80/20 ratio. This lets your cat get used to the new litter’s smell and texture first.
Stage 2 (Days 3-4): Equal parts new and old litter to boost adaptation
Adjust the ratio to 1:1 new and old litter, mixing it well to prevent separation. Watch how your cat uses the litter box. If it hesitates to dig or doesn’t cover its waste properly—small signs of discomfort—go back to Stage 1 and give it more time to adapt. If your cat acts normal, stick to the 1:1 ratio, top up as needed, and check how well the new litter clumps and controls odors.
Stage 3 (Days 5-6): New litter as the main base, phase out the old litter
Switch to 20% old litter and 80% new litter, mixing it well before use. If your cat uses the box without issues, you can just add fresh new litter after scooping, letting the old litter naturally fade out. If there’s still discomfort, extend this stage by 1 or 2 days.
Stage 4 (Day 7 and onwards): Full switch to new litter
Empty the litter box completely, wash it with clean water, then dry it thoroughly. Add only new litter to a depth of 5 to 8 centimeters. Go back to your regular scooping and topping-up routine, and maintain the litter box as the new litter’s instructions suggest. The switch is now complete.
Key Tips During the Litter Switch
1. Keep the environment the same. Don’t move the litter box, change its surroundings, or alter ventilation. Multiple changes at once will make your cat more stressed.
2. Scoop out soiled clumps at least once or twice a day to keep the litter box clean. This stops bad smells from building up and soiled clumps from breaking apart—both of which can put your cat off using the box.
3. Don’t mix litters with conflicting properties. For the transition, pick litters of the same type with similar clumping mechanisms first. This avoids ruining clumping and odor control.
4. Watch your cat’s litter box habits the whole time—how often it goes, how it digs, and if it covers its waste. If it consistently avoids the box, eliminates in the wrong places, or seems listless, switch back to the old litter immediately. Once it’s back to normal, slow down the transition pace.
5. Make sure the new litter is at the right depth. Seal the bag tightly after opening to stop it from getting damp and clumpy, so it keeps working well for absorption, clumping, and odor control.
6. Kittens and senior cats are more sensitive to change. Lengthen the transition to 10 to 14 days, splitting it into 5 or 6 stages. Also, choose low-dust, fine-grained new litter to protect their respiratory systems and paws.
ЧАСТО ЗАДАВАЕМЫЕ ВОПРОСЫ
What to do if my cat avoids the litter box?
Switch back to the old litter right away and stop the transition. Once your cat uses the box normally for 3 to 5 days, start over from Stage 1—lower the percentage of new litter in each stage and give it more time to adapt. Also, check if the new litter has a strong, unpleasant smell; if so, try a new batch or a different brand.
Can I switch the litter box at the same time as the litter?
Not recommended. Two environmental changes at once will make stress far more likely. Wait until your cat is fully used to the new litter, then place the new litter box next to the old one. Once it’s comfortable with the new box, you can remove the old one.
Are there any special adjustments for switching between different types of litter?
Yes. For example, if switching from tofu litter to mineral litter, cut the percentage of new litter to 10% in Stage 1. If switching from mineral litter to tofu litter, fluff up the mixed litter more during the transition to stop clumps from sticking together.
What to note when switching litter in a multi-cat household?
Follow the rule of one litter box per cat, plus an extra one. Switch the litter in all boxes at the same time, step by step—this stops cats from picking and choosing boxes. Also, scoop out soiled clumps more often to keep all boxes clean.
If the new litter sticks to the bottom or clumps poorly after the switch, is it because my cat isn’t used to it?
Not necessarily. First check if the litter is at the right depth, if the new litter has gotten damp, or if it’s mixed with old litter that has conflicting properties. If these aren’t the issues, then it might be that your cat hasn’t adapted yet.
