So my bunny seems to always be hungry! He is 3 months old. I feed him 3/4 of a cup of pellets, a cup to 2 cups of greens, and he eats a ton of hay...I don't want to over feed him, but he constantly seems hungry! Am I feeding him enough, or should I feed him some more?

What type of pellets and hay are you giving him?  At 3 months, he will still be packing on a lot of calories for growth, so you can feed him higher calorie foods like alfalfa hay and alfalfa pellets.  At 6 months or so, you can start trying to limit his calories, but for now, he's just a growing boy!

Plus he is long hair so he needs more protein

Oh and he's adorable btw!

Baby bunnies NEED unlimited alfalfa hay and alfalfa pellets for rapid growth.  Don;t worry about weight gain for at least a couple more months yet!

Thanks...He is super adorable. That picture is old because he's at least 3 times bigger now, but still ridiculously cute! Well, thanks for all your advice. I just don't want to over feed him.

Yeah i think you can't give bunnies too much hay. I learned that the hard way with a few bouts of ileus...yes i sound like a bad mom but i learned my lesson a long time ago.
Now my three buns get hay all the time. It really is great for their digestive system and I don't think its high in calories or whatever - it's mostly fiber to push things through

You are right, Theresa, grass hay is really important for house buns.  As you mentioned, it helps their digestive system by giving them lots of indigestible fiber to keep their gut moving, and it is low in calories so they can eat as much as they want to.  Hay also gives them lots of chewing, which helps their teeth.  In the wild, rabbits are grazers, and having hay around gives them good mental stimulaiton too.

Theresa - what a cute pic :-) And you're right - grass hay is the most important thing in the adult bunny's diet. It's what keeps their GI Tract moving
