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 fifty 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."
Your cat's water bowlis making her drink less
Studies show pet bowls can carry more bacteria than a toilet seat. Stagnant water breeds biofilm and odors — she can smell it long before you can, so she quietly stops drinking.
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.
Science doesn't lie
Hydration has a huge impact on a cat's health.

"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
Complete her care routine
The fountain handles hydration. These two handle the rest — no toothbrush, no bath.
Fresh Breath Spray
A quick spritz keeps her kisses pleasant — no toothbrush wrestling, no drama.
No-Wash Mousse
Foam in, towel off — a clean, soft coat for cats who'd rather die than bathe.
Ships in the same box as your fountain · covered by the same 30-day guarantee.
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.*
Curiosity wins
The sound and sparkle of moving water pulls her in — sniffing turns into first sips.
The habit forms
She visits the stream on her own, several times a day. The faucet begging stops.
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."
