i don't eat it very much, it makes me really bloated if i don't rinse it about a billion times, it often comes with msg in the seasonings, and its a bit of a pain in the arse to prepare. i doubt its amazingly good for you- its really quite processed, but so is a lot of other stuff.
i don't know how valid his rabbit test was though- like a commenter said, if he put it out dry, it'd be like wood chippings, i woulnd't eat it like that either. also, the rabbits might avoid it because it'd swell up and give them tummy ache as their bodies tried to reconstitute it. i'm pretty sure you shouldn't give some grains to birds for the same reasons.
