Before You Buy
Key Buying Factors
01
Material
Stainless steel is our top recommendation for hygiene and durability. It resists bacteria and is easy to clean. Avoid plastic to prevent feline acne.
02
Capacity
For large cats or multiple cats, choose at least 2 liters (67 oz). Larger tanks need less frequent refilling.
03
Filtration
Multi-stage filtration (mechanical, chemical, biological) removes debris and improves taste. Replace filters regularly.
04
Noise Level
Pumps should be near-silent. Submersible pumps in larger fountains tend to be quieter.
05
Ease of Cleaning
Look for dishwasher-safe parts and wide openings. Simple assembly and disassembly are key.
06
Reliability
Check for pump warranty and owner feedback on longevity. Avoid fountains with frequent motor failures.
Living With It
Care, Cost and Maintenance
Daily Maintenance
Check water level and ensure pump is running. Remove any visible debris from the fountain surface.
Weekly Cleaning
Disassemble and wash all parts with mild soap and warm water. Clean the pump impeller to prevent clogs.
Filter Replacement
Replace filters as recommended by manufacturer (usually every 2-4 weeks). Rinse new filters before use.
Pro tip
We recommend placing the fountain on a mat to catch splashes, and filling only with filtered water to reduce mineral buildup and extend pump life.
Frequently asked questions
How often should I clean my cat's water fountain?
We recommend a full disassembly and wash every week to prevent biofilm and bacteria growth.
Is stainless steel better than plastic for cat fountains?
Yes, stainless steel is non-porous and more hygienic, reducing the risk of feline acne and bacterial buildup.
What size fountain is best for large cats?
For large cats or multiple cats, we suggest at least 2 liters (67 oz) to ensure constant water availability.
Can I use a cordless fountain for my cat?
Cordless fountains offer flexibility but require regular battery changes or charging. Ensure the pump is powerful enough for your cat's needs.
How do I know if my cat is drinking enough water?
Monitor water intake and litter box moisture. A fountain can encourage drinking due to running water's appeal.
