To understand it, you don’t need a biochemistry degree.
All you need to know is this:
Your cat’s body is built out of billions of tiny cells.
Every one of those cells has a fatty outer layer – a membrane – that needs the right balance of fats to stay flexible, hydrated, and calm.
Two families of fats matter most:
Omega-6s – pro-inflammatory (we need some, but not too much)

Omega-3s – anti-inflammatory (these are the “calming” fats, especially EPA & DHA)

In the wild, a cat would get a natural mix of both from fresh prey – organs, fat, even small amounts of fish if they’re near water.
But our indoor cats?
They eat:
Dry kibble that’s been heated and stored for months

Canned foods with just enough fish oil to pass minimum requirements

Treats and toppers loaded with chicken fat or plant oils

Result: most indoor cats get plenty of omega-6s… and not nearly enough stable omega-3s.
That long-term imbalance is the Indoor Omega Gap™:
Years of modern, convenient food quietly starving your cat’s skin and tissues of the calming, anti-inflammatory omega-3s they’re designed to run on.
On the outside, that gap can look like:
Dry, flaky skin

Dull, “dusty” fur

Excessive shedding (hair everywhere)

More frequent hairballs (because dry, irritated skin sheds more fur that gets swallowed)

On the inside, it can contribute to:
Low-grade inflammation in joints

Extra stress on kidneys and heart

“Slowed down” older cats who just don’t move like they used to

Suddenly, Luna’s “mystery” symptoms don’t look random at all.
They look like a pattern.
