All the Scoop Away products appear to have revised their clumping formula. The different Scoop away products seem to vary only by the level of fragrance (scented or not) and level of "microbials". The Multi-Cat formula adds "extra Odor Guard"; presumably this is its anti-microbial agent. Another product adds the silica crystals (with no mention of fragrance or anti-microbial at all).

What's the difference among the four Scoop Away® products?
Scoop Away Plus Crystals: combines moisture absorbing litter with odor trapping crystals to create a tough odor-fighting formula.
Scoop Away Fresh Scent: has an anti-microbial agent that fights the growth of odor-causing bacteria in the litter and has a moisture-activated fragrance.
Scoop Away Unscented: has an anti-microbial agent that fights the growth of odor-causing bacteria in the litter, with no added fragrance.
Scoop Away Multi-Cat Formula: has extra Odor Guard™ agents that fight the growth of odor-causing bacteria in the litter and has a moisture activated fragrance.
Fresh Scent, Unscented and Multi-Cat varieties are made from natural minerals and clays that are 99.9% dust-free and non-toxic to humans and animals. In addition, a gentle bacteria-fighting agent has been added to all Scoop Away varieties. This agent is proven to be safe and effective in fighting odor-causing germs on contact. The agent is odorless, so your cat won't notice it's there. Scoop Away Plus Crystals also contains silica gel as well as natural minerals and clays.
