What should you feed a one month old pet rabbit?

Pellets, and Hay. I'd use Timothy hay, you can use Alphalfa Hay until it gets to be about 5 months, but I'd just get a big thing of Timothy Hay. (Alphalfa is richer than Timothy, It's like how a mothers milk is richer than bottled milk?) Also if you give him/her any greens, (like cabbage or lettuce) make sure they are dark colored greens!! Rabbits can NOT have either lettuce or cabbage because it'll cause diarhea and bloating and he/she can die from that! (I give my bunbun turnips) You should call any vet place and ask them what types of veggies you should give it.
