Pistachio shells--okay or no?

[jemgeck]

Have been throwing fruit and veggie scraps in there, but what about pistachio shells? Would they be beneficial in any way? Would they be harmful in any way? Should I just throw them in there or try to grind them up a bit?

If it were me I wouldn't feed them those type of shells. I just don't see any beneficial value in them. They are very sharp even if you go through all the trouble of grinding them up.
Waste of time and if they do eat them they will fill up on them and not eat the nutritional foods. I personally never feed my girls empty calorie foods.
Just my opinion. Hope that helps.
