Silvery Californian kit
Out of the seven purebred Californian kits we got out of our first breeding, one kit has always been a silvery-gray color.
A little research has indicated that eventually this gray will recede to white and this kit will probably have the best color points out of all of them.
Like in Siamese cats, the dark color points on the extremities of Californian rabbits are due to a form of albinism, resulting from a mutation in tyrosinase, an enzyme involved in melanin production. The mutated enzyme is heat sensitive and fails to work at normal body temperatures but becomes active in the cooler regions of the skin. This results in dark coloration in the cooler parts of the body.
This means if your Cal has some strange dark spots or coloration where it shouldn’t normally be, it’s probably because of cold spots in the environment. Never fear though, with their next molt your rabbit should be back to its original, glorious white.

What beautiful little bunnies!
Awww, they are adorable, and so pretty! Interesting information too!
Thank you!
isn’t she adorable!
I got two new bucks last September. I bred 5 does to them. 3 to Hunter, and 2 to Taylor. All of Hunter’s babies are white with dark points. Taylor’s however, had only one doe with kits. They are all grey. I know the lady 4 generations of my does to be pure bred Californians. But I don’t know this bucks lineage. He is white with perfect dark points.
Any ideas why out of 9 kits, all are grey? They are 10 days old and no color points showing.
