The majority of rabbits diets should be grass/hay and wild plants. Pellets should be viewed as a supplement, not a main food.
Rabbit need to be provided with a variety of safe wild plants. Here are a few places that have great info:
The vast majority of pellets on the market have poor quality ingredients that contribute to gut problems. Pellets should not have ingredients like soybean hulls, wheat feed, soybean meal or molasses
We recommend cold pressed pellets such as Bunny Nature, Hay Box or Meadow Menu
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.
Plastic wrapped bags of hay from pet shops are usually not good enough for rabbits to eat, they're often soft, chopped too short, brownish and the plastic wrap causes them to sweat and mould.
