Maybe you've heard there was a television show called "Mr. Ed" about a horse that could talk. They put peanut butter in the horse's mouth to make him look like he was saying the words that were dubbed in over the video.
I tried to feed Ellie some peanut butter today and it went great! She really liked it a lot. However, she still gagged, retched, and vomited into the blanket I had nearby.
