The world's most famous miniature horse celebrates his first birthday with a new book

When Einstein the miniature horse was born at a farm in New Hampshire last May, people could hardly believe their eyes. The horse weighed just 6-lbs. and was about as tall as a box of Wheaties. Now, almost a year later, Einstein has grown, and is growing up. He’s passed the 15-lb. mark, he’s celebrating his 1st birthday on April 22 and has a new book, A Friend for Einstein, that hits shelves next week.

The children’s book is a cute tale about the little horse’s search for the perfect playmate. Like a princess looking for her prince charming, Einstein meets a lot of duds before finding his perfect match. Horses and cats? Not a match made in heaven – hiss!

Written by the little stallion’s owners, Charles Cantrell and Rachel Wagner, A Friend for Einstein is a sweet story with a purpose: a portion of the author’s proceeds will be donated to the ASPCA’s Equine Fund, which helps horses who’ve been abandoned or cruelly treated. Einstein is a true friend to horses, indeed!
