I thought it could be interesting to see what different people prefer and why. I generally use megazorb, as I find it quite absorbant and I like that it is soft. I know others find huge problems with dust, but I've not really found it to be worse than any other things! If I can't get megazorb for some reason, my next choice is hemp (which I have currently). I don't find it so absorbant, so wee corners (which the hams have, and the mice don't) need more spot cleans between full cage cleanouts, and when I got my first bale of Auboise a few years back thought it looked a bit "prickly", but the beasties don't seem to agree with me!
I have also tried Back-2-Nature, which I did not get on with at all. I thought it was a bit too hard and pellety, and found an awful lot of lumps of plastic in it. I did mention in a topic somewhere I'd been given a sample of the new Back-2-Nature which is now produced in the UK, and didn't find any foreign bodies in it but still think it's a bit hard and lumpy. Carefresh is another thing I've used and given up on, firstly because the lumps are too big, I find that it really is dusty, and it's horribly expensive!
I'm also testing aspen shavings for the first time, which seem lovely and soft. The only "person" to get them in a cleanout so far is George the APD (who does not seem impressed - but I think that was the indignity of being extracted from bed and plonked in a little carrier).
Sooo...what's your favourite and why?
