I've been reading loads of post about vet beds - I find the woodshavings a nightmare and where I get it from it's either too dusty and I have to filter it out or it's very messy. Where is the best place to buy a vet bed from? I was thinking of getting large ones to cover the whole floor space of the cage, as the piggies go in different places to the toilet. I have four cages to fill really. I know they are expensive, but I just wondered where the best place to buy them really? many thanks.
