Questions people ask

Why do cats prefer a water fountain to a bowl?

Cats are instinctively attracted to moving water because in their evolutionary environment, standing water was more likely to harbor bacteria than flowing water from a stream or spring. Moving water also produces sound that attracts cats to drink. Studies of domestic cat water intake show that cats drink more water overall when provided with a recirculating fountain than with a static bowl. Adequate hydration is particularly important for cats because they evolved in arid desert environments and their kidneys are efficient but benefit from higher water intake, especially for preventing urinary tract disease and kidney disease, which are common in domestic cats.

How often should a cat water fountain be cleaned?

A cat water fountain should be disassembled and cleaned fully every 1 to 2 weeks. The bowl and reservoir accumulate slime (biofilm from bacteria that live in water) and mineral deposits from tap water minerals over time. The filter should be replaced every 2 to 4 weeks depending on the water quality and how many cats use the fountain. A fountain that is not cleaned regularly develops biofilm that can cause some cats to stop drinking from it. The pump should be cleaned by removing and rinsing the impeller assembly (the spinning magnet inside the pump) monthly, as hair and debris that slip past the pre-filter accumulate on the impeller and reduce pump performance over time.

Do cat water fountains use a lot of electricity?

Cat water fountain pumps use very little electricity. Most cat water fountain pumps are rated between 2 and 5 watts. At 2 watts, running continuously for 24 hours uses 0.048 kilowatt-hours. At a US average electricity rate of approximately 16 cents per kilowatt-hour, a 2-watt fountain pump costs approximately $0.28 per month or $3.36 per year to run continuously. A 5-watt pump costs approximately $0.70 per month. The electricity cost of running a cat water fountain continuously is negligible for most households.
