I'll post my opinion and then let Karen correct me if I'm wrong! lol

Buns should have free access to hay--but not alfalfa hay. (It has too much calcium(?) for them and can cause problems.) I feed my bun Timothy hay and once in awhile--for a treat--coastal. (It's used as a treat just because it's harder for me to find.)

re: pellets: The vet said that Sophie (she's about 5lbs) should receive no more than one cup per day.

Sophie also recieves parsley and cilantro in the mornings. Fruits and other sugary food are kept to a bare minimum.

Pineapple juice (or papaya juice/tablets) are good for their digestive system. They contain some kind of enzyme that helps to break down hairballs. I usually give (unsweetened) pineapple juice to Sophie once a week. (I'm not sure of the recommended amount for juice--I fill the bottom of her bowl up and let her drink for about 5 minutes. If you use the papaya tablets, I believe the recommended dosage is 1-2 pills--depending on weight--per week.)

I've never heard of grass not being good for bunnies. (They sell bunny grass in the stores.) I would becareful though--there's always the chance that pesticides, etc. could hurt the bun.

The House Rabbit site has some really good info on it...can't remember the link right off hand, but I will look for it.

Hope this helps! I know Karen will have lots of info for ya!!
