Litter Usage by Type
Clumping clay: 28 lbs per cat per month. Most popular — forms scoopable clumps. Crystal/silica: 15 lbs per cat. More absorbent, less tracking, but some cats dislike the texture. Pine/natural: 25 lbs per cat. Eco-friendly, good odor control. Lightweight: 20 lbs per cat. Easier to carry but costs more per pound. Scoop daily and do a full change every 2-4 weeks.
The Litter Box Rule
The golden rule: one litter box per cat, plus one extra. Two cats need 3 boxes. Place boxes in different locations — cats prefer options and may avoid a box that smells like another cat. A covered box gives privacy but traps odors (clean more frequently). Uncovered boxes are easier to maintain and most cats prefer them.
Over a 15-year lifespan, one cat generates about 5,040 lbs of litter waste. Switching from clay to pine or recycled paper reduces environmental impact by 80% while performing comparably.
