The majority of rabbits diets should be grass/hay and wild plants. Pellets should be viewed as a supplement, not a main food.
We highly recommend that people give their rabbits a variety of safe wild plants. Here are a few places that have great info:
Our rabbits love having a handful of Readigrass mixed in with their hay.
We buy our bales of Timothy Hay from
We also love the Ings hay from
It's also worth finding out if you have a local farm shop that sells bales of good quality hay (usually £6-8 for a big bale), this is much cheaper than buying small bags from pet shops. They'll also likely sell big bales of Readigrass/Graze On
Look for nice greenish sweet-smelling hay
