Litter Box Supply Planner
Plan litter changes and estimate monthly litter cost.
About Litter Box Supply Planner
Each box is fully changed about weekly, so monthly litter is multiplied by roughly four and a third weeks, then converted into bags and cost. Scooping daily and replacing litter weekly keeps odor and bacterial load low, so the schedule is as important as the budget.
Formula
Litter Box Supply
Litter/month = boxes x (4.35 changes) x kg per change; bags = liters / bag size
- kg per change
- litter needed for a full replacement of one box
