The only cat water fountain you never clean!

Battery Powered

  • Battery Powered.  No more power cord!  The AquaPurr 4 runs for months on 4 AA batteries.

Flow Control

  • Flow Control.  You asked, we listened.  The AquaPurr 4 has flow control.  You set the amount of water that comes out of the spigot, from a dribble to a stream.

Smaller Size

  • 3.5".  The AquaPurr 4 is just 3.5" across and only 4" tall.

Same great technology

  • Proximity sensor.  The AquaPurr 4 has the same great technology as the AquaPurr eC with a proximity sensor.

Aerator Threads - I've got you covered

  • What can you do to help?

    When you order your AquaPurr, send me a photo of the aerator on your faucet.  That's the part where the water comes out.  Based on that photo, I will know which set of adapters to send to you.


  • Which adapter should you order with your AquaPurr?  

    None!  By sending me a photo of your aerator, I will know which set of adapters to send you.  If those don't fit then we will work together and determine what you need.  Then I will send that adapter free of charge

  • How to remove your aerator:  

    Aerators are removed by unthreading them from the faucet.  Looking down from above the faucet, you will turn the aerator clockwise.

  • How do you measure an adapter size?  
    The instructions!  The instructions have an entire page on faucet thread adapters including a sizing chart.  You may use the sizing chart if we have to work on getting you a different adapter.

  • What to do if you can't install the diverter valve.  

    Call me!  Text me!  I can help.  Send me a picture of your aerator and we will go from there.


  • When you move, I can help!  

    If you need a different adapter when you move to a new place, I'll only charge you $5 to send you the adapter you need.

The AquaPurr Difference

  • Unlike any other cat water fountain.  Goodbye to filters.  Goodbye to refilling.  Goodbye to pumps.  Goodbye to nasty, stale, recirculating water.  The revolutionary AquaPurr provides your cat with fresh water straight from the faucet.

  • Cat triggered.  When your cat steps close to the AquaPurr, they activate the AquaPurr's motion sensor that triggers water flow from the AquaPurr spigot.

  • No recirculating water. Your cat drinks from the AquaPurr spigot, and the water they don't drink flows down the drain.

  • Automatically shuts off.  When your cat steps away, the AquaPurr automatically shuts off in a few seconds.

  • You still have full use of your sink.  Because the AquaPurr connects to your faucet with a diverter valve, you still have full use of your sink when you want it.

Always Fresh Water

The AquaPurr 4 connects to your faucet for fresh water every time.

Cat Triggered

Your cat triggers the flow anytime they want.

Never Clean or Refill

You never clean or refill the AquaPurr 4.

The AquaPurr uses no pump.  Instead, the cat triggers a sensor which opens a valve to let the household water pressure deliver the water to the cat.  What they don't drink just goes down the drain.

Why the AquaPurr is so much better than recirculating fountains

AquaPurr eC

Never needs cleaning

Because the AquaPurr 4 does not recirculate a reservoir of water, the water never gets dirty.

Always clean

Because the AquaPurr 4 does not use a pump there is nothing to foul the water.

Never refill

The AquaPurr 4 never needs to be refilled because the water comes straight from your faucet.


The AquaPurr 4 is silent because it doesn't use a pump to move the water. Instead it uses the water pressure from your faucet.


The AquaPurr 4 is just 3.5" across.

Recirculating fountains

Requires cleaning

The cat saliva mixes with the water and forms slime in the reservoir of water requiring regular cleaning.

Always dirty

The inside of the pump gets slimy which immediately fouls the refilled water.

Always refilling

Recirculating fountains need to be refilled often, usually daily.


Recirculating fountains use a noisy pump to generate the flow of water.  And they get even louder when the unit runs out of water!


Because recirculating fountains need to have a reservoir of water many are very large.
