She's been sleeping a lot lately.
It might be as simple as water.
Cats came from the desert. Their thirst signal barely fires, and still water is the one kind instinct tells them to avoid — so they quietly under-drink for years. KaiShine gives her moving, filtered water she'll actually use, all day, without you thinking about it.

Shipping Information
"She heard the water from the other room and came running. Two weeks in, she drinks every time she walks past it — best hundred bucks I've spent on this cat."
"Hydration is the first thing I ask about at every checkup. For cats that ignore their bowl, a quiet moving-water fountain is the single easiest change owners can make."
"Our 14-year-old grump took three days to trust it, and now it's his spot. His numbers at the vet were the best they've been in years."
She won't tell you she's thirsty.She'll just seem a little off.
Hiding discomfort is instinct — in the wild, a cat that looks weak becomes prey. So low water intake almost never looks dramatic. It looks like a cat who naps a bit more, plays a bit less, and seems basically fine.
Sleeping More, Playing Less
The pounce doesn't come. Play sessions get shorter, then stop. It's easy to file under "she's just getting older."
A Duller, Flakier Coat
Grooming and skin need moisture. When she's running short, the shine is usually the first thing to go.
Small, Hard Litter Clumps
Fewer and firmer clumps than she used to make is one of the clearest at-home clues that less water is going in.
A Dry-Food Diet
Kibble is roughly 10% moisture. The prey cats evolved on is around 70%. That gap has to be closed by drinking — and usually isn't.
Begging At The Tap
She'll cry at a running faucet, drink from your glass, paw the shower — while a full bowl sits untouched three feet away.
Hiding More Than Usual
Cats retreat when something feels off, long before there's anything you could point to.
Every one of these signs can have other causes — some of them serious. If you're seeing them, book a check-up with your vet. KaiShine's job is to make drinking easy at home; it isn't a diagnosis and it isn't a substitute for that visit.
The bowl isn't neutral.It's part of the problem.
You refill it every morning, so it feels solved. But standing water grows a bacterial film within hours and goes flat and warm by lunch. Her nose is far better than yours — she registers all of it, and simply drinks less.
Bacteria & Biofilm Buildup
Still water becomes a breeding ground within hours. That slimy film inside her bowl? A bacteria layer she licks with every single drink.
The Drink-Less Spiral
Cats instinctively avoid stagnant water. When it smells off, she doesn't complain — she simply drinks less, day after day.
Stale By Lunch
Her nose is far more sensitive than yours. The bowl you filled at 7am reads flat, dusty and stale to her by midday.
Warm, Flat, Ignored
Warm still water holds less oxygen and tastes worse. A moving, filtered stream stays cool, fresh and appealing all day.
Kidneys do the quiet work.
A cat's kidneys filter her blood every single day, and they need water to do it. Chronic low intake is one of the few risk factors you can actually influence from home — which is why hydration is the first thing most vets ask about.
Drink More
Cats reliably increase their intake when a still bowl is replaced with moving water.*directional — substantiate with your own testing before launch
Urinary Risk
Low daily water intake is associated with higher urinary-tract risk in cats.

"Is she drinking enough?" You'll finally answer yes.
Cats descend from desert hunters — their thirst signal barely works, and still water reads as unsafe. A moving, filtered stream flips both instincts in her favor.
- Cats naturally drink more from flowing water
- Better hydration supports kidney & urinary health
- Designed to make drinking a habit, not an event
No whisker fatigue. No plastic aftertaste.
Deep bowls press on a cat's ultra-sensitive whiskers, and scratched plastic harbors the film she can smell before you can see it.
- She laps the falling stream — whiskers touch nothing
- 304 stainless: nowhere for slime to hide
- Gentler on chins — helps avoid feline acne
Fill it Sunday. She's covered all week.
3.2 liters is a full week of water for most cats — and the porthole window tells you at a glance when it needs a top-up.
- Refill roughly once a week, even less for one cat
- Perfect for weekends away
- Battery lasts up to 45 days per charge
How to use KaiShine
Two minutes out of the box. No app, no account, no plumbing.
Fill it
Lift the lid, pour in up to 3.2 liters, drop the filter in place.
Place it anywhere
No cord, so it goes where she actually likes to drink — not where the outlet is.
She does the rest
The sensor starts the stream when she walks up. A fresh filter goes in every ~2 months — refills mail themselves, so you never track it.
What to expect
Most cats investigate the moving stream within the first day.*
WEEK 1Curiosity wins
The sound and sparkle of moving water pulls her in — sniffing turns into first sips.
MONTH 1The habit forms
She visits the stream on her own, several times a day. The faucet begging stops.
MONTH 3+Hydration is routine
Steady daily drinking becomes her normal — the foundation vets ask for at every checkup.
*Typical experience from early testing — individual cats vary.
Loved by cat parents (and their cats)
"I set it down, filled it, and she was drinking before I threw the box away. She trots over every time she hears the little stream start. I didn't know she was this thirsty the whole time."
"At her last checkup the vet asked what we'd changed — Patches was in the best shape she's been in years. The only thing we changed was this fountain. She drinks all day like it's a hobby."
"Noodle used to knock glasses off the counter to get at our water. Now he has his own tiny faucet and acts like he owns a café. Wish we'd bought this the day we got him."
"Excuse the terrible photo, she wouldn't stop moving lol. Biscuit ignored every bowl we owned and now I refill this thing weekly. Weekly!! For a cat that 'never drank.'"
"Our 14-year-old grump took three days to trust it. Now it's his spot by the window. The vet was happy with his numbers this year — first time in a while."
"Got it for one kitten, both of them claimed it. One drinks, the other just watches the porthole like it's TV. Battery's been going almost a month and a half."
