A fair comparison puts recurring litter, liners and bags beside the equipment cost over the period you realistically expect to use it.
Monthly formula
Monthly system cost
litter purchases per month x price per purchase
+ liners and bags per month
+ equipment price / expected months of use
Example, not a forecast
| Input | Illustrative value | Replace with |
|---|---|---|
| Litter | $24 every 4 weeks | Your last two receipts and actual interval |
| Bags or liners | $6 per month | Your compatible refill cost |
| Box | $90 over 24 months = $3.75/month | Purchase price and conservative useful life |
| Total | $33.75/month | Your own sum |
The example excludes taxes, shipping, cleaning supplies, replacement parts and veterinary costs. A health-monitoring litter is not a substitute for veterinary diagnosis.
Use cost to reject false savings
- A lower box price can lose if it requires proprietary refills.
- A bulk litter price can lose if storage or lifting does not fit the household.
- An automatic unit can lose if maintenance parts and compatible litter are ignored.
- A subscription can lose if the shipment interval exceeds actual use.
