Katie, I think this actually appeared on the RWAF site or the RAW site, two well know UK sites. I love the stuff the RWAF (Rabbit Welfare Association and Fund) who do some fabulous work with bunnies and the RAW (Rabbit Awareness Week) work all year round but have one week a year dedicated to owners and awareness where they give free vet checks all over the country, advice and competitions. I have them on facebook and I love their news. It is just a guide as all bunnies are difference and I know lots on here don´t eat that much hay or more pellets are aren´t good with veggies but I like to think that this is the ideal but not the definitive and there are some really healthy bunnies with a different diet. A happy, healthy bunny is the who is loved and cared for is the most important thing.
