We are hobby rabbit breeders and use the readigrass for our beautiful rabbits alongside their hay. In fact after talking to other breeders around the concern of hay being a carrier of the VHD Rhd-2 virus we took the decision to move away from hay and use only readigrass. We were buying smaller bags from pet supermarkets, but we then found the 15kg bags and I have to say our rabbits love it. It is great quality, there is none of dust that you get from the hay which means the rabbit is cleaner and my husband can clean and feed the rabbits without a mask for his allergies. I would certainly recommend this to others.
