Carl & Earl - The Indoor Instinct E-Book
Instant download available after purchase
Your cat hasn't read the memo that they're indoor-only.
Every instinct they have — the hunting drive, the need for height, the way they communicate, it comes straight from thousands of years of wild ancestry. They just happen to be expressing it in your living room.
The Indoor Instinct is a 25-entry guide to what's actually running in the background. Not a vet pamphlet. Not a list of things you've been doing wrong. Just genuinely useful things about how your cat experiences the world — the kind of stuff that makes you go "oh, that's what that's about" and immediately want to try something differently.
Inside you'll find things like:
- The real reason your cat ignores toys five minutes after you buy them
- What the slow blink actually means — and how to do it back
- Why cats are hardwired to distrust still water (and the easy fix)
- Why your cat meows at you but almost never at other cats
- The subtle early signs of stress that most owners miss entirely
- And a closing section of facts so strange you'll want to text someone
It's a quick read. It'll change how you see your cat.
Happy cats, happy customers.
"Honestly didn't expect much from an e-book but I couldn't put it down. I learned more about my cat in an hour than I have in three years of owning him."
Verified Customer
"I kept having that 'oh, so THAT'S why he does that' moment over and over. It's not written like a vet manual it's genuinely easy to read and actually interesting."
Verified Customer
"Got this as a bundle with the fountain and read it the same night. It completely reframed how I think about what my cat needs. Wish this existed when I first got her."

Frequently asked questions
Is this just basic cat advice I can find on Google?
Not really. Most of what's online is surface-level symptom advice — "try a different food bowl" or "add more toys." The Indoor Instinct goes deeper into the evolutionary why behind your cat's behaviour, which makes the practical advice actually stick. Once you understand the instinct, you stop guessing.
How long does it take to read?
Most people finish it in one sitting — about 45 minutes to an hour. It's written to be genuinely enjoyable, not dense. You can also dip in and out by topic if there's something specific you want to understand first.
My cat is pretty relaxed and healthy. Is this still useful?
Yes — probably more so. A lot of the guide is about spotting subtle things you'd otherwise miss: early stress signals, environmental gaps, small habits that compound over time. It's more useful as a preventative read than a troubleshooting one.
Is this written for new cat owners or experienced ones?
Both. New owners get a strong foundation fast. Experienced owners tend to have more of those "oh, that explains everything" moments because they have more behaviour to reframe.
How do I access it after purchasing?
Instantly. You'll receive a download link by email as soon as your order is confirmed. It's a PDF you can read on your phone, tablet, or computer — no app needed.
Is this specific to certain breeds?
No. The instincts covered in the guide are universal across domestic cats regardless of breed. Whether you have a Maine Coon or a rescue moggy, the fundamentals apply.
Can I get a refund if it's not what I expected?
Yes. If you read it and genuinely feel it wasn't worth it, reach out within 60 days and we'll refund you in full. No hoops, no questions.
