These coat color patterns can happen in random-bred in addition to purebred cats with both long or quick coats. I love tortoiseshell cats. My fav is a Russian blue tortoise name Julia which I discovered on Instagram. She is so stunning and does have tortitude. My Tortie chose her home. https://trentonlshhv.blogpixi.com/34027371/not-known-facts-about-tortoise-mouth
