- 💎 Silica crystal litter
- 🧹 Litter box routine
You switched to crystal litter because the box still smelled even with daily scooping. Now the questions start: there are no clumps to scoop, so what do you actually do each day, and how do you know when the whole box needs changing?
Here is Petstone's answer for Calitti Crystals Non-Clumping Silica Cat Litter: keep about 2 inches of crystals in the box, remove solid waste every day, top up as needed, and replace all of the crystals once they no longer help control urine odor. Calitti gives no fixed number of weeks, so your nose and your cat decide.
Quick answer
- Fill a clean box with about 2 inches of Calitti Crystals.
- Remove solid waste daily and add fresh crystals to keep the 2-inch depth.
- Replace all of the crystals when they no longer help control urine odor; there is no fixed schedule.
- Wash the empty box with mild, unscented soap at each full change.
- Never flush the crystals; put used litter in the trash.
What Calitti Crystals is
According to the Jeffers product page for Calitti Crystals, the only listed ingredient is silica crystals. The litter is non-clumping: the crystals absorb urine instead of forming clumps. Calitti describes it as 99% dust free, lightweight and low-tracking.
- Unscented: pink granules
- Lavender: purple granules
- 8 lb bag
- Unscented in 2-packs and 4-packs
Most cats prefer unscented litter, according to the Cornell Feline Health Center, so Petstone suggests starting with the unscented pink version.
How much to put in the box
Calitti's directions call for about 2 inches of crystals in a standard litter box. That sits at the top of the 1 to 2 inch range the ASPCA says most cats like. Owners who use crystal litter often report that with too thin a layer, urine reaches the bottom of the box and the smell builds sooner.
Your Calitti Crystals routine
| When | What to do | Source |
|---|---|---|
| Daily | Remove solid waste | Calitti directions (Jeffers) |
| As needed | Add fresh crystals to keep about 2 inches | Calitti directions (Jeffers) |
| When odor control fades | Empty the box and replace all of the crystals | Calitti directions (Jeffers) |
| At each full change | Wash the box with mild, unscented soap, dry it, refill | Cornell, ASPCA |
| Always | Do not flush; keep the bag away from children | Calitti directions (Jeffers) |
How to know it is time to change everything
Calitti's own trigger is simple: replace all of the litter once it no longer controls urine odor. Cornell adds a useful test for any litter: the box should look and smell dry and clean. Watch for these signs:
- A urine smell when you walk into the room, even right after removing solids
- Crystals that look wet, discolored or saturated
- Urine pooling at the bottom of the box
- Your cat hesitating, sniffing and leaving, or going next to the box
Owners who use crystal litter describe full changes anywhere from every week or so to about once a month. The number of cats, the number of boxes and how well the depth is kept up all make a difference, so treat any figure as a starting point, not a rule.
How to do a full change, step by step
- Pour the used crystals into a trash bag and tie it closed. Do not flush them.
- Wash the empty box with warm water and mild, unscented soap.
- Dry the box completely, so the new crystals start dry.
- Pour in fresh Calitti Crystals slowly and low to the box, to about 2 inches.
- Check the box for scratches or cracks; Cornell suggests replacing boxes that stay smelly.
Write the date on a strip of tape on the bag each time you do a full change. After two or three changes, you will know your home's real rhythm.
More than one cat?
Cornell advises one litter box per cat, plus one, and notes that more cats means more frequent changes. With two cats sharing one box, expect to change the crystals sooner than with one cat in two boxes.
Honest limits of crystal litter
Calitti Crystals will not suit every home. Owners of crystal litters, including this one, raise a few recurring points:
- Dust experiences vary; some owners still notice dust when pouring, despite the 99% dust-free claim
- Urine can pool under the crystals if the layer gets too thin
- The crystals feel and sound crunchy, which some cats dislike
- Hard crystals can scuff a soft plastic box over time
Who Calitti Crystals suits, and who should choose something else
✅ A good fit for
- Owners who prefer removing solids and topping up over scooping clumps
- Homes that want a light, low-dust litter (99% dust free, per Calitti)
- Cats that accept a crystal texture
⚠️ Not a good fit for
- Owners who want scoopable clumps
- Anyone who plans to flush used litter
- Cats or kittens that try to eat litter
- Cats that refuse the texture after a slow switch

The ASPCA notes that eating silica gel can cause stomach upset, such as vomiting and diarrhea. If your cat eats litter, call your vet or the ASPCA Animal Poison Control Center at 888-426-4435. See your vet promptly if your cat strains, visits the box often with little result, has blood in the urine, or starts avoiding the box, and for any sign that is persistent, severe or getting worse.

Calitti does not state a duration. It depends on the size of your box, how many cats use it, and how often you do full changes.
Can I flush Calitti Crystals?
No. Calitti says not to flush the crystals. Bag used litter and put it in the trash.
Is the lavender version a good first choice?
