What is a gray and white cat??

Hi there Mister here. Mom googled my color which is gray and white and it doesn't look like I have an official name like the Tortie, Tuxedo and the Tabby and so on. So does anyone know if my color has a name??

I love to drink my water out of this bucket. It fills up with the rain off the roof so it is extra tasty. I am 14 years old but seem to be doing just fine.
