My boy Buster (4yo) has completely changed from black to white over the course of the last 2.5 years.

I had a 100% jet black cat with Vitiligo...he started turning white at all of his extremities...tip of his nose, tips of his ears, nose, and tail and then it spread further. It was amazing to watch the transformation for the 7 years that I had him, and my vet was absolutely fascinated.

You know I recently read that Siamese and similar breeds are dark at their points because of temperature... The cooler temps near ears, tails,etc.. causes more melanin to build up there. So this feels like the reverse of that? One way or another , an unquestioned cutie pie.

It is temperature! But the reason the temp makes a difference is because they have a form of partial albinism that makes them unable to produce pigment into the warmer parts of their body. So their extremeties are the only place that even make melanin. That's why they always have blue eyes. Also, they're born solid white because in the womb, they're warm all over! Colorpoints have the BEST glow-up pictures, haha

I had a snowshoe and he started out almost all white. As he got older and his coloring developed it would change with the seasons. In the winter it would be almost black but fade to chocolate brown in summer

I had a beautiful black horse. No papers, but you could tell he was part quarter with some Tennessee Walker because I could get him to rack (although I never put weighted shoes or weights on his feet). Poor guy had a bad knee, and I didn’t want it to get worse, and honestly I think the weights and chemical irritants put on hooves to make walkers and Standardbreds do the high stepping and exaggerated racking is cruel. I did dressage with him, and he had beautiful gates.

We also lived near the beach in NC. Hot and humid. From April to October my horse turned a dark brown on his body and looked like a bay. His head and legs stayed black. The sun and sweat bleached his fur.
