ohhh thanks everyone!

I didnt know that the grass was high in fibre or that the poo has good things in it for them haha!

the grass eater occasionally vomits first thing in the morning maybe 2 mornings out of the 7....but its almost like dry reaching, i can hear his stomach regurgitatiing but all that comes out is a little bit of saliva....... it only happens first thing in the morning, im thinking he wakes up and they play a bit rough and then it happens maybe its from laying down all night and then suddenly being active........
