Do you think I killed my guinea pig?
I have him a marshmallow and he seemed to really enjoy it. that's not like piggy murder is it?
possibly, marshmallows have ingredients that are bad for them. its ok, you didn't know but next time google foods they can and can't eat. if you aren't sure don't give it to them
Marshmallow is toxic to rabbits and guinea pigs. As much as they enjoy the meal, this type of plant does more harm than good in guinea pigs. Even if your guinea pig died due to feeding it this plant, you cannot blame yourself as you were not aware.
quick!... get rid of the body before the GP-FBI finds out
