How to spoil your pet rabbit
Provide hay.
Rabbits need access to hay 24 hours a day. Hay is great for nesting, and also aids in digestion.
Go to the pet store and pick out a bag of high quality timothy or oat hay. Make sure there's always a few piles of hay present in your rabbit's cage so he can eat and nest as he pleases.
