How the comparison works

Enter two or more purchases of the same tofu litter brand, formula and scent. Use the price for the entire purchase and the quantity in each pack. The number of packs multiplies that quantity once.

Use the price you can actually pay

Enter a price you have checked for the exact selected pack or bundle. Include shipping in that price if you want to compare delivered cost. Include a voucher only when you can use it. The calculator does not check retailer prices, voucher eligibility, availability or delivery.

Keep kilograms and litres separate

Grams convert to kilograms, and millilitres convert to litres. Mass and volume have separate results. We do not convert between them or infer density. Your budget applies to the full purchase price, not to the cost of one pack within a bundle.

What “lowest” means

After you confirm that the purchases contain the same brand and formula, the lowest entered unit price is identified within each dimension and your budget. This is the lowest among your entries, not the cheapest offer on Shopee or the wider market. Close prices may display the same rounded value; calculations use the unrounded value.

Price is one part of the choice

Unit cost does not establish quality, odour control, safety or how long a litter will last. Check the product and retailer details before buying. We provide no pet health or disposal advice.

Shopee listings

Catalogue prices and tracked purchase links come from Shopee affiliate offer data. Each listing shows when it was checked. Price ranges may cover different pack sizes or selections. We show no catalogue unit price unless the price and quantity belong to the same verified selection. The calculator remains separate and uses your own entries.

Confirm the final selected price, stock, shipping and voucher conditions on Shopee. Affiliate-offer availability does not establish stock. Offers that have expired or have not been refreshed within 48 hours lose their purchase button until checked again.
