I have used various brands of silica cat litter, and I think it is very good.
Smell absorbtion depents on how well your cat covers its poo, but it lasts over a week with me, sometimes as mucht as 2 wseeks, with 3 litter trays for 8 cats. All but 1 are outdoor, but if the weather is cold, wet or windy, or if they simply want to get back to bed with us, they will favour the litter tray.

So I am convinced the estimate of lasting a month for a single kitty is accurate.
I quite like it. The only thing is that one of my cats will scratch so violently that the crystals are scattered all over the place, whereas he will not launch as many wood pellets.

 

Is it dangerous at all if they eat it?

 

I have never used a Silica litter, I used Catsan non clumping when mine were wee and then changed to Oko Plus, I still find Oko good (just hoping the two bags I ordered last week are ok :frown

 

We use the silica litter sold at Home Bargains, which at £2.29 per bag is very much a bargain!

I have 2 male kittens (that wee A LOT!) and an adult male cat. The litter does not smell at all and lasts really well. It gradually changes colour (from white to yellow) as it absorbs the urine and there is no moisture left in the tray at all. Our cats all cover their waste really well and it is easy to remove. There is no dust tracked over the floor but they do kick some bits on the floor as they leave the trays and I would suggest not standing on these in bare feet as it hurts

Thats the stuff I just bought loads of! With only one kitty, I think I have about 6 months cat litter stored up
