When I was little, I used to have such a shy, but loveable cat named Rusty. He was, of course, a Red Tabby. My aunt randomly found him in her classroom and decided to give him to my mom and I since we just lost our cat of 8 years, Tiger. For the longest time when we got to know Rusty, he never meowed. Not even once. It wasn't until a few weeks later that he began to speak, and the weirdest thing was that he didn't meow properly. He was literally a stuttering cat. We didn't care and found it very cute. And actually, the best part was that my mom is a stutterer. So the two of them got a long better than anyone else. It was very adorable!
