If you're lucky enough to share your home with more than one cat, Ever Clean's Multiple Cat will provide extra odour fighters for litter trays exposed to high usage. Packed with extra odour fighters that can deal with heavy use litter trays in multiple cat households. For continuous freshness, Ever Clean is effective at eliminating cat urine, faecal and ammonia odours. Our unique activated carbon technology traps and locks in odours thereby eliminating malodour instead of just masking it. Paw-activated fragrance technology releases a fresh scent on demand when the litter tray is in use.
