Print or copy this sheet for the person who buys litter and the person who refills the boxes. Keep one sheet beside the clean supply. Use the same unit throughout: pounds, kilograms, or liters.
Start and end of the month
| Date | Clean litter on hand across all containers | Unit |
|---|---|---|
| Opening stock: ______ | ______ | ______ |
| Closing stock: ______ | ______ | ______ |
Purchases during the month
| Date | Quantity bought | Price paid | Product or receipt note |
|---|---|---|---|
| ______ | ______ | ______ | ______ |
| ______ | ______ | ______ | ______ |
| ______ | ______ | ______ | ______ |
Litter used = opening stock + purchases − closing stock. Example: 8 lb at the start + one 20 lb bag − 11 lb left = 17 lb used. Count every clean storage container at both checks. A transfer between containers does not change the total. The stock calculation already includes top-ups, full refills and spills.
Before the next shop: Amount left ______ · Next full refill likely ______ · Backup bag or pickup date ______. Note a new litter type, new box, or big spill alongside the numbers so a second person can make sense of the change.
For a worked comparison across different box setups and a separate way to estimate the cost of litter consumed, see Cat & Meow’s monthly litter use and cost guide.
