Everflow Replacement Filters — Multi-Stage Fountain Filters

A fountain with an old filter is worse than a plain bowl. Once the carbon is spent, the filter stops removing hair and debris and starts holding onto it — and cats, who are picky about water in a way that borders on unreasonable, notice immediately and stop drinking.

Swap every 2 to 4 weeks. A 4-pack covers roughly three months for a one-cat household; the 8-pack covers about six.

Multi-stage filtration

• Cotton layer — catches fur, litter and food crumbs before they reach the pump
• Activated charcoal — strips the chlorine taste and odour that makes cats reject tap water
