Direct answer: a cat may prefer the movement, freshness or location of tap water. Offer clean water in several suitable places and do not make tap access the only drinking option.
Test the location before buying equipment
Try a wide, clean bowl away from food and litter. Observe whether material, depth or a noisy appliance affects use.
Keep running-water options maintained
A pet fountain needs regular cleaning, filter care and safe cable placement. Follow its instructions and keep a normal bowl available.
Notice increased thirst
Preference is different from suddenly drinking much more. Record the change and contact a vet rather than restricting water.
