Calculator assumptions
- Base litter prices are editorial estimates from Canadian retail shelf scans reviewed on March 21, 2026.
- Litter usage is estimated at roughly 25 pounds per cat per month before any additive effect.
- The additive scenario assumes a 20% reduction in litter waste and a 25% longer change interval.
- These estimates are not a promise of savings; they are planning numbers for comparison.
