I've now watched the whole video. I wish I'd read it as an article, as it was basically watching litter dry...
But having left the stuff for 5 days on a few occasions when I wasn't feeling very well, I would say that their experiment pretty much bears out with my experience of it too.
Interesting that your buns ate it too, nessar. Mine seemed to give up on it quite easily, but then they are quite fussy about hay types.
So now I'm wondering what other litter does that's worse, and if I should actually get this one again when the bag runs out.
Avoid shavings because of health hazards and the terrible smell.
Newspaper you've tried, but fine for buns that dont pee much but not Barney! And smells more than the ones below.
Wood pellets you will have the same 'bad' points you noted about the smartbedz, the crumbling etc. It is very absorbant but its not as good for odour, but it is a lot cheaper.
Megazorb is loads cheaper, doesnt absorb quite as much volume for volume as wood pellets or smartbedz, but you can use more in the tray as its so cheap, weight for weight it probably absorbs the same, or more, as its fairly light. Stops smells well but not as good as smartbedz and doesnt absorb quite as quickly (although this should be fine for buns that pee a normal amount!).
Carefresh smells kind of funny, and is expensive, I went through a small bag (£5) a week, but absorbant and controls odour okay, and is 'fluffy'. I'd probably use it for mice or something in the future.
I havent tried Back 2 Nature as its so expensive.
Hope this helps
Oh and one of mine, Barney, is so fussy with hay. Annabelle will eat anything but not as much as I'd like her to unless its good stuff. I think this was the issue really - it was yummier than the hay and more convenient :roll:
