Stirling is a very precious, stealthy boy and he definitely has the look of silver in him with his gray, wispy fur. He's a little more on the shy side, but once Stirling feels a trusting bond with you, he will allow you to pet him and brush him happily.
Stirling is quite gregarious when it comes to chasing his favorite ball and he loves to be given treats along with TLC. He would likely do very well confidence wise with a companion pet.
