This certainly seemed like a far-out idea, but during the two years I worked on the book, I kept hearing this. The people I was talking to, professional animal communicators, impressed me as being people of education, intelligence and spirituality, and they all said essentially the same thing - that certain animals come up with poetry. I collected half a dozen of these poems, and they are not doggerel, they're real poetry.
Nobody seems exactly sure.
The most popular explanation is that without a doubt animals reincarnate, and they often change from species to species. Many of them have been human beings, and possibly will be again. Perhaps they were human in a former life, and that's where the poetry comes from. As my research went on, I grew braver and decided to devote a chapter to poetry by animals. I made it the last chapter to give my readers the maximum time to get used to anything.
