i just wanted to say i went here http://www.petandgarden.com.au/ and bought a bale of oaten hay and a bale of regular straw hay for my rabbits which i keep in my garden shed (they also sell smaller bags if you don't have a shed) and my rabbits are absolutely in love with the stuff, especially the oaten hay. it is waaaaaay cheaper than the generic eating hay i've been getting from the pet store ($14 for 2kg vs $23 for approx 23kg bale) and the rabbits adore it. they never ate all their pet-store-hay but they finish every last bit of the oaten hay. i hope it isn't possible for rabbits to eat too much hay?!

anyway, the store above is run by really lovely family people, and i highly recommend it!
