Very impressed
I used the EverClean Lavender first, which was really good. In fact the best I've ever tried over the years of having cat family members. Lavender was out of stock so I tried Fast Acting Odour Control and will never go back to anything else, it's that good. My two Ragdoll kittens eat a lot, thus a lot of litter tray use. It only smells for literally few seconds after they've pooped, then smell completely disappears. Never any urine aromas in the air. EverClean is not cheap, but well worth it.
