Living with cats teaches you one thing very quickly:
they have their own preferences, and they are not shy about showing them.
I live in Japan and share my home with two cats.
They are brothers and have been with me since they were kittens.
Now they are both 10 years old.
Even though they grew up together, their personalities—and especially their food preferences—are completely different.
Two Cats, Two Very Different Tastes
One of my cats is curious and eats almost anything.
The other is picky and easily gets bored.
At first, I thought buying the same food every time would be the easiest solution.
But I learned that this doesn’t work well in the long run.
If I keep giving them the same food, they slowly lose interest.
Eventually, they start leaving food in the bowl.

Why I Started Changing Their Food
In Japan, it’s common to buy cat food at supermarkets.
There are many options, but most of them fall into two categories:
- Meat-based flavors
- Fish-based flavors
After trying both, I noticed something very clear:
my cats strongly prefer meat-based food.
So now, when the current bag is about to run out,
I occasionally switch to a different product—usually still meat-based, but from a different brand or recipe.
This small change keeps them interested and eating well.
A Mistake I Made About “Healthy Food”
For many years, I focused on choosing grain-free food.
From when they were about one year old until recently, I believed this was the best option.
However, both of my cats are neutered and live indoors.
Over time, they gained weight more than I expected.
Looking back, I realize I should have paid more attention to:
- Indoor cat formulas
- Weight control or neutered cat formulas
These are designed specifically for cats like mine.

Choosing “high-quality” food is important,
but choosing the right type of food is even more important.
Food and Health: A Simple Idea
In Japan, as well as in China and Korea,
there is a concept called “food and medicine come from the same source.”
It means that what we eat directly affects our health.
I believe this applies to cats as well.
My cats are a bit overweight, but
they have never had any serious illness so far.
Good daily nutrition seems to make a difference.
How I Safely Change Their Food
One important lesson I learned is this:
Never switch cat food suddenly.
When I change their food, I always mix it gradually:
- Day 1–2: mostly old food, a little new food
- Day 3–4: half and half
- Day 5+: mostly new food
This helps avoid digestive problems and makes the transition smoother.
What I Do When They Refuse to Eat
Sometimes, no matter what I try, they just won’t eat.
In those cases, I use simple tricks:
- Add a small amount of treats
- Sprinkle a topping or “furikake” for cats
This usually helps bring their appetite back.
And honestly, it’s understandable—
even humans don’t want to eat the same thing every day.
A Brand That Worked Well for My Cats
Since I live in Japan, I often choose products available locally.
One that my cats consistently like is
Purina ONE Grain-Free.
They eat it well, and it has been easy to include in their rotation.
A Small but Noticeable Change
Because I pay attention to their diet,
I’ve noticed something interesting.
Both of my cats are mixed breeds,
but their coat condition is better than a Siamese cat I used to have in the past.
Their fur looks smooth and healthy.
Food may not be the only factor,
but it clearly plays a role.
Final Thoughts
Changing cat food is not just about variety.
It’s about understanding your cat’s preferences, lifestyle, and health needs.
- Don’t rely on one type of food forever
- Choose formulas that match your cat’s condition
- Change food gradually
- Observe how your cat reacts

Small adjustments can make a big difference over time.
Your cat may not say it in words,
but their behavior will always tell you what works best.
