Frequently Asked Questions
Do cats prefer flowing water fountains over bowls?
Many cats are attracted to moving water because it appears fresher; fountains and trickling modes can encourage more drinking. However, individual preference varies — choose a quieter flow and a comfortable height for whisker relief if your cat is sensitive.
How often should I clean the fountain or change filters?
Clean the bowl and pump every 1–2 weeks to prevent biofilm and hair buildup. Replace disposable charcoal/foam filters per manufacturer guidance (commonly every 2–4 weeks) or sooner if you notice odor or reduced flow.
Are gravity-fed dispensers better than pumped fountains?
Gravity dispensers are quieter and avoid pump failures, but they can have slower flow and larger footprints. Pumped fountains provide circulating filtration and more attractive flows for picky drinkers but require occasional pump maintenance.
