Pet water fountains are popular because moving water encourages many cats to drink more, which supports kidney and urinary health. Yet plenty of cats sniff a new fountain and walk away, or stop using one they liked before. The cause is usually something small, such as noise, a dirty pump, placement near the litter box or whiskers touching the rim.

## Give your cat time to adjust

Cats are cautious about new objects, especially ones that hum and move. Keep the old water bowl available next to the fountain for the first week or two so your cat never has to choose between being thirsty and trying something unfamiliar.

Some cats accept a fountain more quickly if it is first used with the pump turned off, as a still bowl, and then switched on once they drink from it comfortably.

## Check for noise and vibration

A pump that rattles, gurgles or buzzes can scare sensitive cats. Low water levels are the most common cause of noise, because the pump starts pulling in air, so top up the fountain before it runs low.

Place the fountain on a stable, level surface rather than a hollow cabinet or wooden floorboard that amplifies vibration. A silicone mat under the fountain can dampen the hum in a quiet apartment.

## Keep it clean

Cats have a strong sense of smell and avoid water that tastes stale. Biofilm builds up on the pump, tubes and bowl within days, and filters that are overdue for replacement can give water an off odour your cat notices long before you do.

Clean the fountain and pump weekly with warm water and unscented dish soap, rinse thoroughly and replace filters on the manufacturer's schedule. Stainless steel and ceramic fountains are easier to keep fresh than scratched plastic, which traps residue.

## Rethink placement

Many cats prefer not to drink right next to where they eat and avoid water near the litter box entirely. In small apartments these often end up close together, so move the fountain to a separate quiet spot away from food and litter.

Choose a place where your cat can see the room while drinking, not a narrow corner or a busy walkway. Offering a second water source in another room also increases how much many cats drink.

## Consider the design and your cat's health

Some cats dislike their whiskers brushing the sides of deep bowls, or do not like the splash of a tall stream. Fountains with a wide, shallow drinking area or a gentle flow over a flat surface suit these cats better.

If your cat suddenly drinks much more or much less than usual, urinates more often, or seems lethargic, contact your vet. Changes in thirst can be an early sign of health problems, and a fountain should not delay a check-up.
