Flopping Fish, 3-pack
★ 4.4493 shopper reviews
Smart pet products · original designer
Our touch-activated toys wake when a paw lands, our fountain swaps stale water for fresh on its own, and our upkeep tools cover the time between missions — everything we build is engineered for the hours your pets spend home alone.
“What happens to pets when their owners aren't home?”
We built Petgravity on that one question. Our answer became a fleet: toys with motion sensors that hold the day shift, water that refreshes itself, and grooming gear for the reunion — so an empty apartment stops being empty hours.
The stations
Every instrument we make docks into one of five stations around your home.
Fish that flop, birds that chirp, shrimp that jump — touch-activated plush that fights boredom for you.

Flagship instrument
Most fountains push the same water in circles past a foam filter. Ours drains what's been drunk from into a separate wastewater tank and refills the 304 steel bowl fresh from a 3.5 L reservoir — so the bowl never holds second-hand water, and you never buy a filter from us or anyone else.

Fleet telemetry
The full fleet
Seventeen instruments across five stations — every one is a click from the launchpad.
Field reports
I set the ball to smart mode before leaving for work and the camera tells the story: every couple of hours she pats it awake, hunts it down the hallway, and naps like a professional. The 6 p.m. zoomies are gone.
The fountain's waste tank sold me. I emptied it the first week, looked at what was in there, and understood exactly what my old circulating fountain had been serving him. He drinks noticeably more now.
Our orange tabby declared war on the taiyaki within the hour. It jumps, he flips it, it jumps again — ten minutes of pure combat, then they both rest. Best sixteen dollars this apartment has spent.
The gray cuckoo chirps once and both cats materialize from opposite ends of the flat. I hooked it to a wand like the box suggests and now 'bird duty' is a scheduled evening event here.
I have clipped exactly one quick in my life and swore never again. The depth dial on this clipper is the reason I groom at home now — set it to 2 mm, squeeze, done, nobody screams, nobody bleeds.
Terrier destroyed every plush we owned in under a week. The oxford fish is on month three, second cover, snack pocket still doing its dirty motivational work. He guards it like a bone.
Ground control notes
The hunt is a circuit: stalk, chase, catch, kick. Motion toys close it — here is what to look for and what to skip.

No — that is the point of the sensors. The plush toys and Sprint balls stay dormant until a touch wakes them, run a short play cycle, then go back to sleep. At night an untouched toy is just a toy. If your cat patrols at 3 a.m. and wakes it, smart mode is doing its job a little too well; park the toy in a drawer at bedtime.
The toys carry 150 mAh cells — enough for days of touch-triggered play sessions on one charge, since they only run when activated. Charge everything on a basic 5V/1A adapter; fast chargers can confuse small batteries. The fountain also ships mostly discharged, so give any new arrival a full charge before judging it.
It is a different philosophy. Filter fountains recirculate the same water past foam; our system drains used water into a separate 1.5 L wastewater tank and refills fresh from the 3.5 L clean tank, so the bowl never holds second-hand water. You give up buying filters; you take on emptying the waste tank. Most owners call that trade a win.
Almost certainly not — cats distrust novelty on principle. Place the toy where ambushes happen naturally (behind furniture, along the hallway), let it lie dormant for a day so it stops being new, and let the first activation be the cat's own doing. Most skeptics convert within a week; the rotation trick in our motion-toy guide finishes the job.
The motors lift out. Unzip, remove the motor unit and catnip pouch, and the plush shell washes normally; the dog fish goes further with a fully replaceable oxford cover. Dry completely before reassembly — batteries dislike damp bunks.
For most cats: the flopping fish 3-pack — three fish, three temperaments served, highest hit rate in the fleet. For a ball-motivated cat or a multi-cat house, the Sprint set. For dogs, there is exactly one correct answer and it is armored in oxford cloth.
At Petgravity we design interactive cat toys and smart pet gear for the reality most cats actually live in: indoors, alone for stretches of the day, with a hunting instinct that never got the memo. Our fleet covers every station of that life — touch-activated flopping fish cat toys and chirping flapping bird toys with catnip, the Speedy Sprint smart cat toy ball with two speeds and a wake-on-touch mode, and an automatic cat water fountain with a 304 stainless steel bowl that swaps stale water for fresh instead of recirculating it past a filter.
Every powered toy we sell is USB rechargeable — 150 mAh cells, Type-C or USB cables in the box, and not a single AA battery to buy. Our motion sensors keep the toys dormant until a paw lands, which means play happens on the cat's schedule and the battery lasts for days of ambushes. For multi-pet homes we extend the range to bite-resistant electric fish dog toys in washable oxford cloth, and to the grooming side of our bench: an adjustable cat nail clipper with four depth stops, self-cleaning slicker brushes with a built-in water tank, and thick alcohol-free pet cotton tissues for paws, ears and eye corners.
We are Petgravity Technology, an original designer and manufacturer of smart pet products — the team behind the rotating ball and the lifelike kicker toy line, sold through our official storefront, where every item on this site checks out. Prices, stock and delivery run at that counter; here we keep the specifications, honest shopper ratings and serving advice in one calm, readable place.
Whether you are here for an interactive kitten toy that survives real claws, a cat water dispenser that finally beats the dripping tap, or a boredom plan for the hours between breakfast and your key in the lock — our answer to our founding question is the same. What happens to pets when their owners aren't home? With our instruments in orbit: play, water, rest, repeat.
Every instrument in our catalog is one click from the launchpad — the countdown is already running.
