Ceramic and plastic water fountains that encourage cats to drink more with filtered running water.
Cats evolved in arid environments and have a low thirst drive; running water triggers drinking behavior that still water does not. A cat water fountain with a flow rate that produces visible movement encourages more water intake than a standing water bowl. Ceramic fountains are heavier and harder for cats to knock over than plastic, and ceramic does not develop the biofilm scratches that harbor bacteria as plastic ages. A carbon filter removes chlorine taste and odor from tap water; filters should be replaced every 2 to 4 weeks depending on household water quality and cat count. This section covers cat water fountains by material, filter type, tank capacity and motor noise level in decibels.

Multi-cat water fountains are evaluated by water capacity (minimum 80 oz for 2 cats, 150 oz or more for 3 to 4 cats), number of drinking stations or surface area to allow multiple cats to drink simultaneously, filtration capacity for higher water throughput, pump durability for continuous high-use operation, ease of refilling large reservoirs and price.

Cat water fountains are evaluated by water capacity (40 oz is adequate for one cat, larger for multi-cat), filtration system (carbon filter, foam pre-filter, ion exchange resin), pump noise level, ease of cleaning (dishwasher-safe components), material (BPA-free plastic vs stainless steel vs ceramic), flow options (stream vs waterfall vs bubbling) and price.

Ceramic cat water fountains are evaluated by ceramic type (glazed porcelain vs unglazed stoneware vs food-safe lead-free glaze), whether all water-contact surfaces are ceramic or only the bowl, dishwasher safety, weight and stability (ceramic is heavier and more stable than plastic), capacity and price.

Large cat water fountains are evaluated by reservoir capacity (100 oz minimum for 2 to 3 cats, 150 oz for 3 to 4 cats), number of drinking surfaces for multiple simultaneous users, refill mechanism (top-fill vs remove-reservoir), how easily the large reservoir is cleaned, filter capacity for higher volume use and price.

Quiet cat water fountains are evaluated by pump noise level (rated in dB, under 40 dB is near-silent in a quiet room), flow style effect on noise (waterfall style produces more splash noise than a fully submersed bubbling style), whether the pump impeller is ceramic for quieter operation, structural vibration dampening, and price.

Stainless steel cat water fountains are evaluated by steel grade (304 food-grade vs 201), whether all water-contact surfaces are steel (some are plastic with a steel bowl only), capacity, filter type, pump accessibility for cleaning, dishwasher safety for steel components and price.
