A cat that won't drink from its fountain has yet to accept the new machine. At the spot you've chosen, your cat is meeting an unfamiliar object that adds its own sound to the room. Start by separating refusal of this fountain from a change in overall drinking.

Your cat's drinking habits beyond the fountain
Consider your cat's usual drinking routine across the home. It might pass the fountain to drink at its old bowl, or lean over your water glass while the machine sits unused.
International Cat Care says that not seeing your cat drink need not be worrying if its drinking habits are unchanged and it otherwise seems well.1 Less drinking overall or drinking beyond the usual pattern—report these changes, or concerns about insufficient water, to your veterinary team.1

Why won't my cat drink from the fountain?
Begin with the room you put it in and the space immediately around it.
The AAFP/ISFM environmental guidelines recommend separate locations for food and water.2 In their 2020 review, Delgado and Dantas wrote that a preference for that separation had not been demonstrated experimentally.3 Move the fountain away from the food dish.
A quiet spot away from doors, noisy appliances, walkways, and litter boxes is International Cat Care's suggested location. Where possible, allow access from several directions so your cat can drink while facing into the room.1
The battery-powered HAPAW cat fountain isn't tied to an outlet location; in battery mode, its sensor starts the water as your cat approaches. Walk through a possible location carrying laundry or opening the nearby door. Check whether you step past the drinking area or swing the door into the space beside it. Picture your cat approaching, including the direction its body would face.
International Cat Care advises introducing new water resources gradually and explains that fountain noise varies and can affect sound-sensitive cats. Wait for your cat to sniff the casing and walk away before you try a different setting.
Listen near the fountain yourself. Turn off a nearby appliance to hear the machine separately. Change one thing at a time, such as the location or a setting, so you can connect the next approach with that change.
How to get your cat to drink from a water fountain
Place the empty fountain in its intended spot with the motor off, and give your cat time to investigate.1 In International Cat Care's sequence, water is added once the cat is comfortable, and the motor is switched on last. Sit on a chair a few steps away instead of standing over the machine.
Throughout the introduction, offer the other water bowls in their familiar places. Let your cat choose whether to walk closer, and don't carry it to the fountain or press its paw into the water.
With water added, a comfortable approach includes pausing beside the drinking area rather than immediately backing away. Your cat should be able to stay there before you try the next stage.
Your cat may back away once the motor starts. Hesitation is a cue to return to the preceding stage and allow your cat to approach there again. A short note such as “walked over while off; backed away after motor started” records the sequence.
A fountain your cat has stopped using
Start with your cat's last familiar approach to the machine and work outward through the room. Remember where it stood to drink and which route it took. Compare that picture with the space around the fountain today before changing the fountain again.
The room may have changed even though the machine has not. Consider a moved fountain, rearranged furniture, or a new animal in the home. Think back to what changed around the time you noticed the refusal, such as a chair moved into the approach.
International Cat Care notes that some fountains become louder with low water levels and that mold and bacteria accumulating in a container may affect the water's taste.1 Wash the container and replace the water.
Check the water level and watch whether water reaches the drinking area normally.
FAQ
When will my cat get used to a new water fountain?
There is no fixed number of days to plan around. Use your cat's relaxed approach to the fountain as the cue to advance.
Will my cat eventually use the fountain?
Not every cat will use a fountain. You may reach a point where your cat continues choosing its familiar bowl and shows no interest in the machine. Put that bowl in a quiet, accessible location.
