Can access to too much fresh grass hurt my rabbits? I built an outside run 2' x 8' and I was surprised when my 2 pound Netherland Dwarf ate all the grass down to nothing, (didn't touch the hay I put in there). I give fresh grass all the time and they seem fine, but in much smaller amounts. Can't see how a 2 lb rabbit ate all that fresh grass, looks like he ate at least twice his weight in grass, I hope he doesn't explode.
