Frequently asked questions
How often should I change the filter?

Can I use the fountain without a filter?
Yes, but the water will not stay as fresh, and you may need to clean more frequently.
Is stainless steel better than plastic?
Yes, stainless steel is less porous, reducing bacterial growth and eliminating plastic taste.
How long does a battery-powered fountain last on a charge?
Typically 7-14 days depending on usage; check manufacturer specs.
Are these fountains safe for kittens?
Most are safe, but choose one with a low-flow setting or shallow basin to prevent accidents.
