How Do You Feed Two Cats Two Different Diets?

One Bowl, Two Cats, and a Daily Crime
Anyone with more than one cat knows the scene.
The overweight cat finishes his portion in seconds, then calmly walks over and
finishes his housemate's dinner too. The shy cat retreats, eats less each week,
and the guardian ends up standing watch over mealtimes like a referee. Half of
all cats live in multi-cat households, which makes this small daily theft a
widespread problem with real consequences: obesity for one animal, malnutrition
for another, and no way to manage a special diet when every bowl is community
property.
The Peanutcat EGG-1, made by HUBPLATFORM, a
company based in Busan, South Korea, approaches the problem with a simple
mechanism. Each cat wears a small RFID recognition tag, and the feeder opens
only when the designated cat approaches. To every other cat in the house, the
food simply stays sealed. The device earned a CES Innovation Award as an
Honoree in the pet technology category, but its origins are less corporate than
that suggests: the team behind it spent seven years rescuing and fostering
abandoned cats, and tested the design with the 19 cats in their own care.
A Feeder Built From Rescue Experience
That background shaped the product's
priorities. The smart cat feeder dispenses personalized meals matched to each
cat's health profile, age, and dietary needs, addressing overeating and
underfeeding at the same time. Guardians control everything through an app,
where feeding schedules, portions, and each cat's eating data are logged and
visible at a glance. For moments when a phone is out of reach, physical analog
buttons on the device allow immediate operation — a practical detail many
app-dependent devices omit.
Food safety received unusual attention. A
real-time UV sterilization sensor suppresses bacterial growth inside the food
container, keeping kibble fresh around the clock, and the design responds
directly to real incidents of contaminated feed harming cats. The feeder stores
up to two months of food, closes its lid automatically, and includes side
barriers so a second cat cannot ambush from the flanks while the rightful diner
eats. The whole unit uses a modular design that comes apart for easy cleaning,
and its height adjusts to suit cats of different sizes and ages.
Small Functions With Practical Purposes
Several smaller features round out the system.
A guardian voice playback function calls each cat to meals in the owner's own
recorded voice, useful when guardians are away at work. A slow-feeder option
paces cats that gulp their food, which relates directly to one of the product's
measured results. During testing with real households, refined through a
research project with Busan Techno Park, the outcomes were specific:
underweight cats reached a healthy weight, overweight cats lost weight safely,
and the frequency of vomiting among test cats dropped from two to three times
daily to less than once per week.
Those numbers matter because they move the
device from convenience gadget to health tool. Feeding data collected per cat
also gives veterinarians something concrete to review, since a cat that quietly
stops eating is often showing the first sign of illness, and a per-cat log
catches that change days before a busy household would notice.
What Individual Recognition Changes for Pet Care
The EGG-1 reflects a broader direction in pet
technology: treating animals in a household as individuals rather than a group.
Feeding is where that shift matters most, because so many feline health
problems, from obesity to kidney disease, are managed primarily through diet. A
device that guarantees the right cat eats the right food in the right amount
makes prescription diets and weight programs actually enforceable, something
guardians previously achieved only by feeding cats in separate locked rooms.
There are practical limits to note. Each cat
must wear the RFID tag for recognition to work, the system suits dry food
storage rather than wet food, and app features depend on a stable connection.
For single-cat homes, a simpler feeder does the job. But for the millions of
households referring daily bowl disputes, the device addresses a problem that
was previously solved with patience, vigilance, and closed doors — and,
according to its testing, solves it measurably better.
