I'm posting this for my sister, her new bunny is 1yr old she has had him for a month now and he has started sneezing ! He has been to the vet( rabbit savvy) and they have said he is very fit and healthy and prob has an allergy to hay !!!!! she has gone through process of eliminating litter etc so looks like it is the hay, tried several different types but still sneezing. I have heard about Dodson and horrell "just grass" does anyone use this and do you think it would help ? Would love any feed back on this before she buys it off Internet. Thanks guys x
