Cash has really started to change colors. He was a golden dun like his daddy. He is almost a grulla color on his shoulder now. We are calling him a "dirty dun". I can hardly wait until next spring to see what color he really is. Cat's dam was registered as a buckskin and she turned gray with red flecks. I have to check to see what colors she came out of. According to the color book you have to have at least one gray parent to get gray. I was worried Cat would change color, he still is his pretty dun color. It is so hard trying to get pictures of horses that follow you!
