Possibly found a Chartreux in our line of strays 🙂
Kaia, who looks like a Chartreux
We have a lot of stray cats -- or more like, we found a stray cat (tortoiseshell), and she had many kittens and made herself an extensive family. We've kept some, and given some away. What's really great is that they all somehow know better than to inter-mate with each other. Especially the little matriarch, she's the smartest of them all.
But anyway, there were a lot of males that came around for her various litters, two of them were gray ones. We caught one and placed him in another neighborhood, he was huge, but loud and affectionate. In her second or third litter, she had a blue-gray male, who was named 'Stitch', he started out a brilliant kitten, but something happened to him, and now his head is permanently tilted to the right side.. we checked his neck and there was no damage there, we don't know.. but he's large like the description, but is also loud.
Some of the other litters that Peek-a-Boo (original matriarch cat) had, ended up with those blue-gray kittens. One of her litters included a blue female and a black and orange tortoiseshell (like her mother). Those two grew up and were rather small adults, but had the same stocky build, very quiet 'mews', and rounded heads.
Since our cats come from strays we never hoped to divine a breed-line in any of them, but I realllyy think that some of them have the Chartreux blood in them.
Our little blue female just fits too much of the description. We thought it was interesting that sometimes she'll open her mouth like in a meow and nothing will come out. I'm excited now because it'd be really nice to know some of the breeds that make up all of our cats. She also has that thick short hair, not thin like her mother or the other cats. She's very friendly. So, I really think she is part Chartreux 🙂
