With 2, 3, or 4+ cats, odors don't just add up—they multiply exponentially. Standard litters can't keep up. Activated carbon tackles multi-cat odor at the molecular level, handling what other solutions can't.
Multi-cat households face compounded odor challenges. With 2, 3, 4, or more cats, odors don't just add up—they multiply. Multiple litter boxes, territorial marking, and concentrated waste create an overwhelming smell that traditional litters and deodorizers simply can't handle. Purrify's industrial-strength activated carbon absorbs odors at the molecular level, giving you the power to enjoy a fresh home no matter how many cats you have.

Works immediately across all litter boxes
Safe for all your cats, no matter how many
Less expensive than buying premium litter for every box
3 litter boxes recommended
Add 2-3 tablespoons of Purrify per box, refresh every 3-4 days
4-5 litter boxes recommended
Add 3-4 tablespoons per box, refresh every 2-3 days for optimal results
6+ litter boxes recommended
Add 4-5 tablespoons per box, refresh daily. Consider our bulk sizes for cost savings
Distribute litter boxes across different areas of your home. This reduces territorial competition and allows Purrify to work more effectively by preventing odor concentration in one location.
3 cats, 4 litter boxes
"With three cats, my house used to smell terrible no matter what expensive litter I tried. Purrify completely transformed my home! Now guests don't even know I have multiple cats. I use it in all four boxes and it's been life-changing."
5 cats (rescue colony)
"I foster cats and currently have five. The odor was overwhelming until I discovered Purrify. Now I can manage six litter boxes without the house smelling like a shelter. It's also way more affordable than buying premium litter for every box. Absolute game-changer for multi-cat homes!"
Follow this 5-step system to eliminate odor from 2, 3, 4, or more cats and keep your home fresh.
Time needed: 20 minutes setup, then daily maintenance
Follow the golden rule: one litter box per cat, plus one extra. For 3 cats, you need 4 boxes. Spread them across different rooms to prevent odor concentration.
Pro tip: Place boxes in low-traffic areas where cats feel secure but with good ventilation.
Add 3-4 inches of litter per box. Multi-cat households need slightly more depth since boxes get used more frequently throughout the day.
Sprinkle 3-4 tablespoons of Purrify per box for households with 2-3 cats. For 4+ cats, use 4-5 tablespoons. Mix the carbon into the top layer of litter.
Pro tip: For 5+ cats, consider the bulk size for better value.
Multi-cat households generate more waste faster. Twice-daily scooping prevents ammonia buildup and keeps all cats happy to use their boxes.
Top up each box with 1-2 tablespoons of activated carbon mid-week. Complete litter changes every 1-2 weeks depending on usage.
