Hello from Greycoat Research,

Today, we would like to share one important feeding habit that many guardians may be overlooking.

It is free-feeding — leaving food available all day.

Based on consultation data collected by Greycoat Research,
we have observed a meaningful difference in health outcomes related to feeding style.

So far, we have conducted more than 3,500 one-on-one consultations with cat guardians.

Among these cases, cats that were free-fed showed a rate of both chronic kidney disease and chronic pancreatitis that was more than three times higher, compared with cats that were fed on a scheduled, portion-controlled basis.

This does not prove a direct cause-and-effect relationship.
However, it strongly suggests that daily eating habits may play an important role in kidney and pancreatic health.

Free-feeding is not always necessary

Unless a cat is already in an advanced stage of kidney disease
(Stage 3 or Stage 4, where weight loss and muscle loss must be managed very carefully),

we generally recommend two or three meals per day, rather than unlimited access to food.

Short, gentle fasting periods can support healthier metabolic rhythms and cellular balance.

If scheduled feeding is difficult in multi-cat households

We understand that strict meal control is not always realistic when caring for multiple cats.

In that case, one simple and practical option is:

removing all food bowls while you sleep (about 7 hours at night).

Even this small change can help create a short fasting window.

What happens during a short fasting period?

During mild fasting, the cat’s body begins to activate a metabolic pathway called AMPK.

AMPK is closely involved in:

• cellular energy regulation
• removal of unnecessary or damaged components inside cells
• cellular housekeeping and renewal processes

These processes are important for maintaining long-term cellular health.

For cats living with chronic conditions such as kidney disease,
a healthier cellular environment may help support long-term stability.

Constant abundance is not always better

Continuous and unrestricted feeding is not always the healthiest option.

In many biological systems, a small and controlled deficit can be more beneficial than constant excess.

You do not need to change everything at once.

Starting with nighttime feeding habits, or simply creating a more regular meal schedule,
can be a practical first step.

Small changes in daily eating patterns can make a meaningful difference in long-term kidney and metabolic health.

We hope this small support helps you continue caring for your cat with confidence.

Thank you, Greycoat Research
