A spare pump for my ideal fountain

I'm really happy with the Hydr. Finally, I can drink water that's always fresh! We cats are very particular about clean water. With this backup pump, the Hydr will last a long time again. This pump refreshes my water every half hour. That's how it should be! I would absolutely love to keep drinking from the Hydr. Could I have another pump for the tastiest water?

  • Filter:change every 10 days.
  • Every 2–3 weeks:Flush the fountain with natural cleaning vinegar to prevent limescale build-up.
  • Pump filter:Also clean the plastic filter at the bottom of the Hydr pump with natural vinegar or a bio soap solution.

This way the water always stays clean for your cat, and the pump lasts longer!

This is why your cat doesn't drink as much

Cats don't drink much because they originally lived in dry regions. They didn't need much water. Therefore, your cat naturally experiences few thirst cues. Because your domestic cat has a different diet, it should drink more. Hydr encourages your cat to drink more often. This is beneficial for all cats, and especially for cats with kidney problems or bladder stones.

The best water for your cat

Cats love running water. They associate it with clean water. The Hydr backup pump is included with the Hydr drinking fountain. This fountain mimics a gentle, flowing stream. This encourages your cat to drink more often, which is good for their health. Cats rarely experience thirst signals. The Hydr pump refreshes your cat's water every half hour. Finally, water your cat finds refreshing enough to take extra sips!

Hygiene for your cat, convenience for you

Thanks to its cordless design, the Hydr backup pump can be placed anywhere in your home. Besides refreshing the water with the pump, the Hydr fountain also provides fresh water in other ways. A built-in UVC lamp and 4-channel filters keep the water free of bacteria. This way, your cat always has access to delicious and safe drinking water. The Hydr backup pump means you don't have to replace the entire Hydr when your old pump reaches the end of its life.
