Whitewhisker is a tom with an unknown description.
In the Field Guide Arc
- Whitewhisker is mentioned by an apprentice of SkyClan with the name of Sparrowpaw. The apprentice explains to Clovertail that he learned the sky-drop technique. While explaining, Sparrowpaw says that Whitewhisker was his enemy for the day. The apprentice says that Whitewhisker took forever, but when he finally walked underneath the branch where Sparrowpaw was, he dropped down and attempted to land on his back.
- Sparrowpaw explains to Clovertail that Whitewhisker was fine after training. He tells her that his mentor, Sharpclaw had told him that the apprentice was nowhere near the tom, although Sparrowpaw claims that he felt his tail brush against him, and goes on to say that it would be a huge shock for any invading cats.
- "Today, Whitewhisker was pretending to be my enemy. So after I'd been waiting up there for about a moon, not breathing or anything, Whitewhisker walked along the path. When he was right underneath my branch, I let myself fall straight down, like Sharpclaw said—he wanted my belly to land on Whitewhisker's back so that I knocked him over."
