My last lot of hay was from Dust Free. I cant remember which quantity I ordered but it does explain it all on the website. It is nice hay, and arrives next day.. My only gripe is that it's not very long strands so tends to flatten the minute you put it out and having ordered the soft cut ( because after Wally's eye removal I'm now paranoid about stalks! ) was a bit annoyed to find some extremely stiff stalky bits in it. I'm using the Dust free and the carefully sorted by me ( for stalks ) hay for pets hay at the moment, I don't think I'll ever find the perfect hay, I'm too fussy! the Dust Free is definitely the lowest in dust I've come across, doesn't make me sneeze at all.
