| ||For the potential companion in the Wastelad holotape game, see Mr. Pebbles (Wastelad).|
Mr. Pebbles was the first cat launched into space.
A Persian house cat, Mr. Pebbles was the first animal sent into space by the United States Space Administration in 1961. This diverges from our own timeline, where a Russian dog named Laika was the first.
Mr. Pebbles is mentioned on posters scattered throughout the world in Fallout 4 and Fallout 76, and appears in Fallout Shelter. Mr. Pebbles also appears as a possible companion in the holotape game Wastelad.
