I'm not 100& sure but i know it can cause diarrhea.I assume thats not just because of the water content though, as then surely cucumber would be bad too? I'm confused with you know.
Iceberg is one of the lowest green foods in nutrients so it isn't the best greens from a nutrition point of view, your best to stick with dark green. We feed veggies to give added vitamin C.
so really its not bad for them/wont make them ill to eat it,as long as they have other greens as well
Iceberg can give them the runs and this can make them poorly quite quickly.
It's not gonna kill them if they eat a bit (mine have had small pieces in the past), but steer clear where you canIf I'm buying pre-packed salads, I always choose the ones without iceberg
But why iceberg has this effect but not cucumber I don't know though!
Cucumber actually upsets one of my piggies' tummies though I don't know why because the other two love it, so I don't give it very often.
As for lettuce of any kind I thought lettuce had a soporific effect so not sure why they are allowed any lettuce to be quite honest, I never gave any of my previous piggies any lettuce of any description, but have done since reading this forum, except iceberg rolleyes
