Pam mentioned gas: to tell if your bunny has gas you can get down on the floor beside her and press your ear against her side/belly. You should be able to hear light "swishy" watery sounds, about every 2-4 seconds or so for my bunnies is normal. Loud gurgling indicates gas, whereas silence indicates stasis (both are serious problems; you can read about these and other important bunny health issues on the HRS website,
http://www.rabbit.org, to name one great site). It's good to do this test often enough, particularly at first, to get a sense of what normal belly sounds are like. Coco recently suffered from a bit of gas, most likely due to being on antibiotics for an infection, and giving him gentle tummy rubs made him feel much better.
(I just noticed you've posted here thousands of times - compared to my measly 11 as a newbie, LOL - so more than likely you know everything I've said in my post already! Maybe it will prove helpful to newer/less experienced members, so I'll leave it up anyway.
