Living zero-waste with cats is absolutely achievable. Here are practical, tested strategies from cat owners who've made the switch.
The Big Three
Litter, food packaging, and vet waste account for the majority of cat-related household waste. Tackle these first for maximum impact: switch to compostable liners, buy food in bulk or with recyclable packaging, and use digital vet records when possible.
Litter System Overhaul
Use plant-based litter (wood pellets, corn, wheat, or tofu) — all compostable. Add certified compostable liners to make disposal easy and complete. Compost the result (non-edible garden only) or use municipal compost services.
Food and Treats
Buy cat food in recyclable cans over plastic pouches. TerraCycle accepts hard-to-recycle pet food packaging. Buy treats in bulk with minimal packaging. Grow cat grass at home — easy and zero packaging.
Toy and Accessory Choices
Choose toys made from natural materials (wool, cotton, wood) over plastic. DIY cat toys from cardboard, string, and fabric scraps. Buy second-hand scratching posts and cat trees when possible. Choose ceramic or stainless steel bowls over plastic.

Near-zero-waste is achievable; absolute zero is extremely difficult. Focus on the high-impact items (litter, food packaging) and don't let perfect be the enemy of good.
Cat hair itself is compostable. Collect it and add to your compost bin or garden — birds also use it for nesting material if left outside.
Some owners use diatomaceous earth as a non-chemical option. For serious infestations, conventional treatments may be necessary — consult your vet on the safest approach.
