Veterinary organizations worldwide agree: one tray is never enough. EcoPetBox gives you the flexible, eco-friendly second tray that finally makes it easy to follow that advice.
See EcoPetBoxOne litter box per cat — plus one extra. This is the international veterinary standard. Most households don't follow it — not because they don't care, but because a second permanent plastic box feels unnecessary.
The Cat+1 Rule
Cats are fastidious creatures. They avoid dirty or crowded spaces — and when they do, the results are unpredictable. The N+1 rule exists because it works. Providing a second tray prevents stress, avoids territory problems, and keeps your home cleaner.
The challenge: buying a second bulky plastic box feels wasteful. And it creates double the cleaning work. That's exactly the gap EcoPetBox fills — a lightweight, use-and-recycle cardboard tray that makes having a second box effortless.
"One litter box per cat, plus one additional — this is the standard we recommend to prevent behavioural issues and reduce stress in multi-cat and single-cat households alike."
— Cornell Feline Health Center & International Cat CareThe Problem With Plastic
The old plastic box is not as clean as it looks. Here's what most cat owners don't know:
Every scratch from a cat's claws creates micro-grooves in plastic where bacteria nest. No amount of scrubbing fully eliminates them — they accumulate over time, potentially causing urinary tract infections.
Studies have found PFAS in plastic pet products. These synthetic compounds leach from containers into your pet's environment — and can enter their bloodstream. They don't break down. Ever.
Plastic is porous at the molecular level. After months of use, it permanently retains odours. That's why most owners replace their tray every 2–3 years — yet the old one sits in landfill for 450 years.
Made from pressed recycled cardboard — no plastic, no coatings, no synthetic compounds. No micro-grooves where bacteria hide. No chemical residue. You use it, then recycle or compost it. That's the entire lifecycle. Clean by design.
"Paper alternatives have none of these complications. No plastic. No chemical coatings. No endless battle against odour absorption. Just pressed recycled paper that offers a breathable, moisture-resistant surface. Use it, compost it, done."
When You Need It
EcoPetBox isn't just a second tray — it's the flexible one you reach for when life doesn't follow a schedule.
Visiting family for the weekend with your cat? A flat-packed EcoPetBox sets up in 30 seconds, fits in your bag, and gets recycled at checkout. No hauling a plastic box through hotel lobbies.
Urinary infection, post-surgery recovery, or contagious illness — your cat needs to be isolated. One temporary EcoPetBox handles the situation, then gets disposed of hygienically. No permanent equipment for a temporary need.
Three cats means four trays by the vet standard. Three permanent plastic boxes plus one rotating EcoPetBox meets the guideline — without overwhelming your home or your cleaning routine.
Introducing a new cat? Behavioural research shows that the right litter setup during those first 2–4 critical weeks prevents long-term territorial problems. The EcoPetBox covers the transition — then disappears when it's no longer needed.
A lightweight cardboard tray that your mother can replace herself, without lifting heavy plastic or scrubbing on her knees. That's not just convenience — it's independence and dignity for both owner and cat.
Sunday evening, your main tray needs cleaning and you're out of litter until Monday. One EcoPetBox in the cupboard solves it in 30 seconds — and stops your cat from making other arrangements.

The Ecological Truth
Most cat owners replace their plastic tray every 2–3 years. Every single one sits in landfill for centuries. There's a better way.
A plastic litter tray you buy today will outlast your great-great-grandchildren. Most households replace theirs every 2–3 years — meaning over a cat's lifetime, 5–7 plastic trays go to landfill.
EcoPetBox composts completely in 2–4 months — or enters standard paper recycling. Made from recycled materials, it avoids fresh raw resources entirely. Temporary situations deserve temporary solutions.
