"A cat rarely tells you she is sick. She shows you, a little at a time, in her habits."

From Chapter 1
Cover of My Cat Longevity: The Sunday Check Method, from Den Harper Cats
I · The problem

She looked fine. That's exactly the problem.

She hides it on purpose

In the wild, a cat who looks weak gets picked off, so cats learned to hide pain. A sore cat rarely limps or cries. She sleeps a little more, skips one jump, eats a little slower. Each change is tiny, and each one is easy to miss.

It gets called "just old age"

Thirstier. Thinner. Louder at night. Those are three of the signs owners most often explain away. Sometimes it really is age. But they're also early signs of the kidney, thyroid and other problems that are common in older cats.

Then it's urgent, all at once

When the small signs slip by, the first real clue can be a crisis: a cat who stops eating, hides, or can't jump at all. That's when a visit turns urgent and expensive at the same time, and when owners say "I should have seen something."

None of that is your fault. Cats are very, very good at hiding. The answer isn't more worry, it's a small habit: know her normal, check it once a week, and you'll see the changes while they're still small, when your vet has the most ways to help.

The method · The Sunday Check

Seven things. Five minutes. Once a week.

The whole book is built around one habit, the 7 W's. Each has its own chapter: what's normal, what's a warning, and exactly how to check it at home with your eyes, your hands and a kitchen scale.

V · What this book gets right

The honest version, before you buy

What it does well

It turns worry into a routine. Instead of wondering whether that extra drink or skipped jump means anything, you check seven things once a week and write them down. When something changes, the triage tags tell you how fast to act, and the Vet Visit Planner helps you walk in with notes instead of guesses. Everything is written from veterinary guidelines and research, in plain English.

What it does not promise

It isn't a vet, and it doesn't replace yours. Some illnesses give no warning at all, and even good checkups can miss things. No book can promise your cat a number of years. What it can do is help you catch what can be caught, earlier, and know which signs mean go today.

VI · Is it for you

Written for a specific cat owner

This book is for you if

  • Your cat is 7 or older, or you want to be ready before she is
  • You've caught yourself saying "she's just getting older"
  • You want to know which signs can't wait, and which can
  • You'd rather catch things early than face a surprise emergency bill
  • You want one clear weekly routine instead of scattered internet advice

It is not for you if

  • You want to diagnose or treat your cat yourself
  • You're looking for home remedies to use instead of a vet
  • You need a kitten-training or breed guide
Den Harper, host of the Den Harper Cats channel
"Not to turn you into a vet, but to help you notice, so you can act early, ask good questions, and give your cat the most good years possible."
Den Harper · Host of Den Harper Cats

Den Harper Cats is a YouTube channel for people who share their home with an older cat. Every video, and this book, turns veterinary guidelines and research into simple steps you can use at home tonight.

Den is the channel's on-screen host, a digital presenter, and he isn't a vet. That's why the book sticks to what the vet guidelines and research say, and tells you exactly when to call yours.

VII · Questions

Before you ask

My vet already sees her once a year. Why do I need this?

Your vet sees her for a short visit. You see her every day. A lot can change in a year, and cats hide it well. The Sunday Check turns what you see at home into simple notes, so you can spot a change sooner and give your vet something real to work with. The book also covers why the vet guidelines suggest a check every six months for cats over 10.

Isn't this just more internet advice?

It's written from veterinary guidelines and published research, with a full source list at the back. And it never asks you to replace your vet. Its job is to help you notice, then tell you how fast to call.

My cat is already 15. Is it too late?

No. Most of the book is about older cats: the common senior problems, an easier home, feeding, comfort, and the later years. The Sunday Check works at any age, and it matters more the older she gets.

Do I need any special equipment?

A kitchen or baby scale helps for weighing, and the book shows how to do it with a bathroom scale too. Everything else is your eyes, your hands and about five minutes a week.

What if money is tight?

Chapter 28 is about exactly that: spending wisely on her care, what to ask about costs, and why catching problems early is usually the cheaper path. The Vet Visit Planner also helps you make the most of every visit.

Can I read it on my tablet or phone?

Yes. The book comes as a PDF and an EPUB. The PDF looks like the printed page and prints cleanly at home. The EPUB is made for phones and e-readers like Kindle, Kobo and Apple Books, and the text resizes to whatever is easiest for you. The 6 bonuses are print-ready PDFs, each with an EPUB reading copy too.

How is it delivered? Is checkout secure?

Checkout runs through a secure payment page. Your download links arrive right away on the confirmation page and in your email.

She can't tell you. Now you'll know how to look.

Seven things, five minutes, once a week. Ready to read tonight and start this Sunday.
