I get mine from local farms and it has a very strong fragrance to it. As soon as it's in their hutch they go straight for it and then we won't see them for hours. I once filled it so full they couldn't get inside, all I could see was a bunny body with the head buried inside the hay tugging and eating it. Eventually he fell asleep with his head buried in the hay, lol. It's also really cheap, just £2 a bag and they easily go through a bag and a half within a week. As for this American stuff I dunno, why bother buying something overseas for something that's been born in the UK. That's just going a bit too far unless you can't get any decent quality hay from a local pet shop and don't have any farms nearby you can easily get to.
