How Colorpoint Cats Change the Color of their Fur Over Time
Throughout their lives, color-pointed cats change their coloration pattern quite a bit. The process of this change is extremely interesting and it is entirely based on genetics. In fact, it is a mutation that leads to their coloration to begin with.This mutation is temperature sensitive and it affects an enzyme in the metabolic pathway between tyrosine and the final pigment. As a result, pigment production becomes dependent on the cat’s body temperature. Higher temperatures will inhibit production, while lower ones will allow it.Color-pointed cats have darker extremities (with various patterns) because their body temperature is lower in these areas. They present lighter fur on the rest of their bodies because the local temperature is higher there.However, please note that temperature distribution over the cat’s body depends on a wide variety of factors. As such, it varies from one individual to another, but also throughout the cat’s life. This local temperature map is one of the reasons why there is a very large diversity of color-pointed cats.

Changes in Body Temperature Determine a Change in Color
Since color-pointed cats are genetically wired to change their color due to fluctuations in their body temperature, they are essentially a living heat map. Here a few of the factors that typically cause these fluctuations and what you can expect:Age

Local Injuries
When a cat suffers local injuries like scratches, bumps, and bruises, scar tissue is formed. In these areas, the body temperature will be slightly lower because the tissue will not be as efficient in conducting heat. As a result, color-pointed cats will get darker fur in the areas where they suffered these injuries.Diseases
Diseases cause dramatic temperature fluctuations in a cat’s body. A large number of acute diseases cause fever, while chronic diseases usually lead to a general decrease in the cat’s body temperature.These changes will be visible in color-pointed cats, at least to a certain degree. If the temperature change is maintained for a longer period of time, then the pigment changes will have the time to come up.Do you have a color-pointed cat?

I have two siblings that are half ragdoll and half tabby, both approximately two years old. Louis, the brother, had looked lighter orange and creamy. I really thought it was my imagination! Them being floppy and cuddly now makes sense after what I've been reading about them. I love them dearly!

Great information! I have two (red) colorpoints - one is definitely a cream point (Giovanni) and Armani likely is as well although it's hard to know whether he is a cream or a flame point. I'd love to share pictures with you. I see your email above so I'll send a few to you. Thanks for sharing - it's hard to find good side by sides of the changes that happen within many colorpointed cats.

They're all such beauties! 🙂

Beautiful photos of color transitions in these Ragdolls, some are very dramatic that I would not have predicted. My Simon, a blue eyed white, did not transition, other than having a faint tinge of yellow on the bridge of his nose that is barely noticeable.

I have a seal point lynx kitten who has changed so much! I’d love for you to see her! How can I submit pictures to you?

When my late baby Gandalf the Grey was older we would get him the lion cut in the Summer months. As his coat grew back in, every other year his back would shift between being all white to almost all greyand then back to almost all white the following year. My lil kaleidoscope! He was a blue mitted boy.
Great article Jenny, very informative & oh all those precious colorful fluffy snuggly babies!! <3 <3
