true in terms of research, but im just going off experience.
plus shavings/sawdust irritate my lungs ans set off my asthma within the first 5 minutes of messng with it, i wouldnt really like to live on it 24/7 being a rat or other small animal, breathing it in all the time.
my friend was always at the vets with her first 3 boys(i had the other 4 from the litter, kept on bedxcel then aubiose,then magazorb) and when she changed from shavings(she used them for her gerbils too) to bedxcel(cardboard squares) and since then has only had a flare up in one of the boys in over a year.
i can only go on what ive seen and experienced.
megazorb is very messy, but in the last few months its changed, its in bigger pieces, and paler in colur with practically no odour or dust, alot of people have noticed it on here www.fancyrats.co.uk
