For cats weeing outside the litter tray

You haven't failed. You've been fixing the wrong problem.

Vet guidelines don't treat "weeing outside the tray" as one problem: the first thing they work out is whether it's a puddle or a spray, because the fixes are completely different.

Why "I've tried everything" so often made no difference

You've mopped, scrubbed and washed the duvet again. You've moved the tray, changed the litter, bought the spray and plugged in the diffuser. The vet said "it's behavioural" and sent you home. And you're still finding wee, still smelling it when you walk in, still wondering if anyone at home has started saying the word "rehome".

Here's what most advice leaves out.

A puddle and a spray are two different problems

A puddle is your cat going to the toilet in the wrong place. A spray is your cat leaving a message. More trays and new litter can help a puddle and do nothing for a spray. That's why one thing "worked for everyone online" and not for you.

There are 5 possible causes, and each product covers one

International vet guidelines group house-soiling into a handful of causes: the body, the tray itself, stress and tension between cats, territory, and a spot that has become the toilet. A spray, a diffuser or a new litter covers one of them at most. If your cat's reason is a different one, it can't help, however much you spend.

Your cat isn't doing it to spite you

The same vet guidelines are clear: house-soiling isn't about spite or anger at you. It's a cat telling you one of its needs isn't being met. Once you know which one, you know what to change, and punishment (which only adds stress) is never part of it.

The Puddle-or-Spray method

Find the cause first. Then fix that cause, one small step a day.

The same order vets and behaviour researchers use, turned into something you can do at home tonight.

  1. Check (about 3 minutes)

    14 questions about what you've seen: where, how much, which surface, what's changed at home. Because research shows no single sign tells a puddle from a spray, the check combines your answers into your cat's most likely type and cause. Anything that needs a vet comes up first, in red.

  2. Start tonight

    Your result gives you 3 things to do before bed, so the next 24 hours already start differently. Then your 21-day plan: one small step a day, about 5–10 minutes, each with a short "why this works".

  3. Track, then stay or switch

    Note each accident in the tracker (it takes seconds). At day 7 and day 14 it tells you whether you're on the right plan or should move to the next most likely cause. No more guessing, no more buying the next thing on the shelf.

Your questions

I've tried everything already. Why would this be different?
Because almost everything on sale treats "weeing outside the tray" as one problem. The check starts where vet guidelines start: is it a puddle or a spray, and which of 5 causes is most likely? Then you work on that cause, with a tracker that tells you at day 7 and 14 whether to stay on it or switch. It's the order that's different, not one more product.
My vet said "it's behavioural". Is this for me?
Yes, this is exactly where the plan starts. Your vet has done the most important part: ruling out illness. "Behavioural" covers several different causes, and that's what the check helps you narrow down.
I live in a small flat. I can't have a tray in every room.
You don't need to. Every tray tip in the plan has a small-space version, and many steps have nothing to do with trays at all (spraying, tension between cats, the spot itself).
The plug-in diffuser didn't work for us. Do you use those?
No. We don't sell or rely on diffusers. Research on them is mixed, and they target one cause at most. If you want to use one, talk to your vet.
Is this a diagnosis? Does it replace my vet?
No. It gives you the most likely starting point, based on what vets and researchers have published. Weeing outside the tray can be a urinary problem, so the check sends you to your vet first whenever your answers suggest it.
We have more than one cat. Does it still work?
Yes. The check asks about every cat in the home, and tension between cats has its own plan. You'll also see an optional Multi-Cat & Outside-Cat Module at checkout if that's your situation.
How long will it take?
The check takes about 3 minutes, tonight's actions a few minutes, then about 5–10 minutes a day. Every cat is different, so we can't promise a timeline: the tracker shows you honestly what's changing.
Is it a subscription? What do I get, exactly?
No subscription, ever. One payment of £24, VAT included. You get the PDFs to download straight after payment, plus a copy by email.
What if it isn't right for us?
Email us within 30 days and we'll refund you in full. No forms, no questions.

Tonight can be the last night you're guessing.

Find your cat's most likely cause in 3 minutes, do the first 3 actions before bed, and follow one small step a day from there.
