■ The catch — co-equal billing, always
Setup is a chore. It's a taller multi-part stainless tower that takes 7+ minutes to assemble and clean versus a couple of minutes for a simple bowl — and the extra capacity is more to scrub.

Traps — this verdict avoids
Dry-pump burnout
Never let a submersible pump run dry — it's the #1 cause of dead fountains. Cordless models (Dockstream, Eversweet, Capsule) can run dry silently every 1-4 weeks between charges if you ignore the app alert.
The filter tax
A cheap fountain can be pricey to own. Annual replacement-filter spend ran from ~$9 (PetSafe) to ~$100 (Petlibro) in Cats.com's 17-model test — sometimes inverse to the sticker price.
Plastic biofilm
Scratched plastic traps bacteria and can cause feline chin acne. Stainless and ceramic resist it, but every fountain still needs a weekly bowl scrub and a pump deep-clean every 2-4 weeks.
