Nicole Böhm, from Germany, adopted two kittens in 2016. One of them, Elli, used to be a black-and-white tuxedo cat. However, Nicole noticed that Elli's fur was starting to turn white. Elli was diagnosed with vitiligo, a rare skin and hair condition that causes the loss of pigmentation. Over time, Elli's patches of white grew bigger, and she transformed into a white cat with a few black marks. Nicole keeps her followers updated on Elli's transformations through her Instagram account, while Elli's sister Rosie remains unchanged. Despite her appearance, Elli's personality remains the same.
