A good friend of mine is a snake owner. Her and her husband have 6 of them. They are all constrictors of some type, none are poisonous. Recently she celebrated her birthday and another friend of hers bought a life like snake cake to the party. She was thrilled. I did not think of taking pictures but when I got home I found some pictures that were very much like her cake and I have them below.
During my search I found some other interesting snake cakes.
Albinos, color and pattern mutations of snakes and other reptiles
I had to add the next one, not that it looked so real but it looked so yummy.
