I like the idea.. But just now, I imagined @yasha2802 calling for the kitty time after time if she can't find him..? Like he's hiding somewhere and she wants him to come to her..?
What about Fire?
Fire played an important role in the traditions of Native Americans and was present in all ceremonies and rituals. Fire acts as a Messenger and is a gift from the Great Spirit. Smoke for the fire was used to cleanses sacred items, such as drums, shakers, pipes, before ceremonial use. Fire symbolized the heart of the People and its smoke, which could also be created in a pipe, carried prayers to the Great Spirit. The Fire Symbol represents cleansing and renewal because out of the ashes of a fire comes new growth and new thoughts and ideas.
He has a 'flame' on his forehead and he is the color of smoke (and where there is smoke, there is Fire!) . He is also a new growth in your family, and I am sure he will invoke many new thoughts and ideas.
Seems like a perfect fit!
"Fire!..... Fire! ... Fire!..." I don't think the neighbours will appreciate it..! LOL But it is such a good idea for a name! Especially since he indeed has a flame-shaped mark on his forehead.
