Daily Cat Litter Usage Calculator
Estimates the grams of litter scooped out per day from how many cats share the box: roughly 150 g for one cat, 270 g for two and 360 g for three.

Daily litter consumption per cat
An adult cat gets rid of something like 50–70 g of litter per day once you add up the waste (urine + feces) and the clumps you scoop out. The rest is just arithmetic. A 4 kg bag covers roughly 4,000 ÷ 60 ≈ 67 days with one cat. Got more than one? Tack on about 30% per extra cat rather than doubling, since they share the same tray and the math never runs in a straight line. The litter you pick matters a lot too. Silica gel never gets scooped, so you swap the whole tray every 14–20 days; clumping bentonite piles up more daily waste because you keep pulling out the wet clumps; and plant-based granules (corn, pine, tofu) land somewhere in the middle while being biodegradable. Persians and other long-haired cats scatter litter past the edge of the tray, so they effectively burn a few extra grams a day.
Applications
A daily estimate lets pet shops manage stock once they know the average bag rotation per customer. It helps cat owners plan monthly spend, weigh recurring subscription delivery against a single purchase, compare cost per day by litter type, and gauge specific demand by breed, since a Persian goes through more than a Siamese thanks to all that fur tracking. Shelters and catteries juggling several trays find it just as useful.
FAQ
Why isn't 2 cats = double the litter? They share the same substrate, and only fresh waste actually eats into the mass. Figure on about 30% more per added cat, not a full 100%.
Which litter type goes further? Silica gel. You never scoop it, just empty the whole tray every 2–3 weeks. It costs more up front, but its daily consumption (g/day) comes out the lowest.
Does breed really matter? It does. Long-haired cats like the Persian or Maine Coon pick up more litter on their paws and coat, which pushes up the effective daily loss. Budget another 10–15% over a short-haired breed.

Unit Skin Friction (Beta Method)
Calculate a pile's unit skin friction in granular soil by the beta method, f_s = β·σ'_v, from the coefficient β (dimensionless) and the vertical effective stress σ'_v at the considered point (kPa). The β method (effective-stress method) is the modern, rational way to estimate pile skin friction in GRANULAR soils (sands) and in clays in effective-stress terms. It starts from the principle that side friction is like any interface friction: the friction stress is the NORMAL stress to the surface (the soil horizontal stress, K_s·σ'_v) times the tangent of the interface friction angle (tan δ). Grouping these two factors into a single coefficient β = K_s·tan δ, the unit friction is simply β·σ'_v. The coefficient β typically ranges 0.2-0.5 for sands (and more for driven piles, which raise K_s by displacing soil). The great advantage of the β method is using EFFECTIVE stress (growing with depth), capturing that friction increases with depth — though there is a limit (the 'critical depth', above which friction stops growing, a still-debated phenomenon). Integrating f_s·perimeter along the length gives the total side resistance. Enter the beta coefficient and the vertical effective stress.
