Rocky was Guy when we got him, he started out as Lucky but DH changed it to Rocky a few days later cause he kept boxing him with his paws.

Hot Shot had that name since birth so we left it since he responded to it and he was almost 3.  We do usually call him Hot.  It does get confusing tho when I am trying to keep Rocky away from the stove when it is hot.  I will say  "Its Hot" and either Rocky will go look for Hot or Hot will come running when he hears his name, lol.
