Cat litter odor remover made from steam treated coconut shells. No perfume.

We recommend the quarterly subscription: 3 bags every 3 months, with shipping included to most areas. The annual prepay is the best value: 12 bags for the year, delivered 4 at a time every 4 months. One bag is the simple start, with nothing to renew. It is the same Large bag in all three.

For one or two cats and one litter box, a Large bag lasts about 30 days. The quarterly subscription delivers 3 bags every 3 months, and the annual prepay delivers 4 bags every 4 months, so each delivery covers the time until the next one. Add Purrify whenever the box starts to smell again.

You pay once for the year, and the 12 bags are delivered 4 at a time, every 4 months. The annual prepay renews every 12 months and charges the yearly price again until you cancel. Cancelling stops the next renewal.

Yes. Clay, clumping, crystal, tofu, pine or walnut, any brand. Sprinkle 2 tablespoons of Purrify per litter box on fresh litter and mix gently. It does not interfere with clumping or scooping.

A one-time bag or the free trial bag (Canada only) is covered for 30 days from delivery. On a subscription, your first shipment is covered for 30 days from the day it is delivered. You get one window, counted from that first delivery. On a prepaid year, your first shipment is covered for 30 days from the day it is delivered, in one window. If you ask within those 30 days, you get your whole yearly payment back and your remaining prepaid boxes are cancelled.

Ask your veterinarian before changing litter or adding a litter additive. Cornell lists dusty litter among suspected asthma triggers. Purrify is for odor control; it is not a treatment for asthma or protection against lung disease. Avoid breathing in dust when handling litter or granules.

Yes. Shipping is included to most addresses on any size plan, because three bags travel together in one box. A single bag ships at the live rate shown at checkout, added to the price.
