Anyone heard of 'Grazeon'?

Sent mum to the saddlers to pick me up some megazorb and bless her she had a look at the hays they had there. Accoring to the lady there, quite a lot of bunny keepers buy this stuff called 'Grazeon'. It's 7.10 a bag (mum says it's quite big) but I've never heard of it and I was wondering if any of you have (and just how big is the bag?)
They also had 'big' bags of readigrass for 10.50......

I have used graze on and ready grass have had no problem with either

i use readigrass as a treat they love it!smells lovely too:lol:
