Most cat's take to PrettyLitter immediately, but some cats have a harder time transitioning. This happens if your cat doesn't recognize PrettyLitter's new texture, color, or (lack of) smell. Luckily we have some tips to help with the transition! Try taking one poop and one urine clump from the old litter and put into the new PrettyLitter fill. Your cat will recognize the familiar smell and know this is still their bathroom. This has been really successful in transitioning our feline family members to PrettyLitter!
Another method would be to fill your litter box with 75% PrettyLitter and add a 25% layer of the old litter to the top. Your cat will mix it in themselves and then you can use 100% PrettyLitter next month when you replace it!
