Sir Whiskers

Sir Whiskers was the name of a strayed black cat encountered by SPARTAN-IV0492 on numerous occasions aboard the IU Horn of Plenty throughout the Upsilon Andromedae Incident in Halo: Infection. It was a rare survivor of the Flood outbreak, and it was noted for its mysterious appearances in nearly every mission throughout Infection. Upon completing the game on normal difficulty or harder, the player will encounter the cat during the final level, and will bring the cat with him upon escaping.
