The time Sparks went yellow

Sparks went yellow once. It all started one morning when Calum was looking at the cats sitting on the window isle (there favorite spot) when he noticed Sparks went yellow. "Its time for a bath" he said and took her off to the bathtub. There was a lot of meowing and some hissing from the bathroom but in an hours time  came out with a clean cat. Kitty looked at Sparks and so did the rest of us and we were amazed, astonished and shocked. All of the yellow was gone making Sparks a black and white cat once again. I went to put Sparks back on the window isle when I noticed that Kitty had turned yellow!
