Turkish Van cats eat in their dining room at the Van Cat Research Center on February 8, 2018 in Van, Turkey. The famous Turkish Van Cat is one of the oldest domestic cats known, having lived in the Lake Van region of Eastern Turkey for centuries. The Turkish Van Cat has a distinct look with an all white coat sometimes just with a spot of color. The breed has three eye colors, blue, yellow and green, which are sometimes mismatched. The Van Cat research center was founded in 1992 with the objective of protecting the breed from gradual extinction. The facility provides health care and studies the breeds genetics.
