Chartreux genetics in the game
True to the real breed standard, the Chartreux comes in exactly one color: blue. But not one shade – a dedicated intensity gene produces light, medium and dark slate coats, so breeding the exact tone you want is its own challenge.
Temperament and shows
Each cat rolls one of six personality types. A confident cat gets a bonus in beauty pageants, a dominant one in agility; breed and coat color do not affect show scores. In real life, the quiet Chartreux is a calm, sturdy all-rounder.
The breed in the real world
The national cat of France, linked by legend to the Grande Chartreuse monastery. The breed’s distinctness was officially recognized in 1977.
FAQ
➜Why does the Chartreux only have one color?
Because the real breed standard permits only blue – from light ash to dark slate grey. The game models this faithfully with a dedicated coat intensity gene.
➜Is the Chartreux good for beginners?
Yes – its genetics are the simplest of the three starter breeds, which makes it a great way to learn breeding basics before tackling the Ragdoll’s color palette.
