I got the sensitive crystals as I was cautious so my cats didn’t have any type of issues with this type of cat liter. This is a wonderful cat liter!! I love how the crystals absorb the orders instantly and I never have that nasty cat smell in my house! With 2 cats a pan of this liter will last 1 full month before it’s ready to change!! This is amazing for my busy life!! I HIGHLY recommend
this! If your cat has any allergies this sensitive crystals would be a perfect choice!! Just remember to put some of your cats used liter in the crystals to help switch over!
