Over the past year, the fur on Kaesea's back, which used to be dark grey, has turned to a sort of reddish-brown.
His doctor says that a lot of older cats lose pigment in their fur and this is what's happening. It's sort of... odd.
I am rarely able to capture it in photos (perhaps he's embarrassed?) but I finally got this one that really shows it.
Most people go grey when they get old. Kaesea? He was grey and is now going brunette. Figures.
