Why it matters
HydroSphere holds 60 oz for cats and small dogs. Plugged in it flows steadily; on its rechargeable battery it switches to motion-activated flow to save power. It comes in black or white.

Pros and cons
Pros
- Cordless option
- Compact
- Known brand
Cons
- 60 oz
- Price
- Motion mode on battery
Limitations to weigh
- Take the fountain apart and clean the pump weekly, and change filters as the maker directs; slime builds up fast in warm rooms.
- Battery fountains only run when charged; motion-sensor modes save power but may not run for dogs that drink quietly.
