I had been recommended Tigerino by my sister who had moved over to silica cat litter with her two cats. The thinking behind this cat litter is that it absorbs the moisture effectively, meaning that unlike normal cat litter, you don't have to scoop out the litter every time the cats have used the toilet. You simply rake it to disperse the urine throughout the litter which will absorb it. The litter trays are filled more deeply than with other cat litters, and the packaging claims that one tray full of litter could last 2-3 weeks without needing changing. (Of course you still need to scoop the faeces - just not the urine)
I found that the litter was initially very effective for odour control because it absorbs the waste so quickly. However, as the white crystals absorb the urine over time they turn an unpleasant yellow, and while they took some time to start smelling, I found the litter to be less effective than my usual cat litter overall. I also found it more expensive as it did not last 2-3 weeks, only a week for my cats, therefore working out more expensive than the clumping litter I was using before.
Worse still, because the cat litter is hard crystals, when the cat flicks the stones onto the floor and you accidentally tread on them in the middle of the night it really hurts!
