My "Big Ugly" is a siamese sable. He's changed drastically but it's amazing how their colors change. My breeder stated that by 5 months their coat color and pattern should be complete. At time I was considering breeding or showing. I finally realized I'm not a breeder or going to shows so the color change doesn't bother me. My opinion is that you really need to know the breed and the line before really start learning to breed or really show. I guess that's why what I've read, it's good to get a bunny at 5 months or older so you know what they really are (coloring) and the personality. I got my bunnies young because I wanted to bond as pets. And get to watch them turn into the Rabbit that they are going to be. How else would I learn about the breed if I don't experience it.
