How much lettuce have you been giving him? A LARGE handful or just a regular one? If they were bloated, it could cause death quickly with few other symptoms. Lettuce can cause bloat, but probably not in appropriate proportions. Otherwise, you'd basically have to be giving him poison to cause them to pass away that quickly. Chances are it was nothing of your doing. I'm so sorry for your loss.
We gave him a small handful once in the morning and again at dinner time, about a half cup total for the whole day. Thank you for your kind words and support!
