OK thank you very much all, and arnoldshirl sorry to hear about your robo, but glad they have recovered
has anyone used this sand
https://www.petsathome.com/shop/en/pets/desert-sand-5kg at all? It would be much easier for me just to just pick this up if it is considered safe. Whilst I totally appreciate the common sense thing I can't afford to work my way through a bunch of different sands before I find a safe one! Though of course I'd never give one if I had bought it and thought it was too dusty! Thank you everyone
