Bests & Worsts Reviews from Amazon

I'm going to go out on a limb here and guess that most, if not all of the positive reviews are based on initial purchase or they haven't used this litter for very long. I have been using it exclusively for almost 6 months (buying it direct from NEON with discount) and I REALLY wanted it to work out. At first, within the first month or so, it was great though expensive to start out and fairly expensive to maintain at 1 bag a week to keep full. There was no smell, the cats really liked it, was soft on their paws and scooped easily. However, the downside is that after about 2-3 months, the silica turns dusty which (1) is not healthy to inhale (for you OR the cats), 2) the silica dust film gets on EVERYTHING and 3) when trying to clean it off the floor, etc., once it gets wet it smears a sticky film over the surface you're trying to clean. At about 5 months, I begin having respiratory issues after spending time in the same room with the litter such as scooping and cleaning and suspected it might be the litter. Finally, after 6 months, the room was completely sanitized, the litter replaced and within a day or 2, no more sneezing, scratchy throat or sinuses. From what I've read about silica, the silica gel used for litter is supposed to be safe but the dust is NOT. On a side note, I did contact the company about some questions I had (not related to this issue) and they were unresponsive. Not a good sign for a company just starting out and trying to form good customer relations. For your cats safety - and yours, I wouldn't recommend buying this litter. I'm now using Worlds Best Cat Litter as the replacement and it's working great.
