關於an overview of pets in Fallout Shelter，參見Fallout Shelter pets。
Cats are a species of small predatory carnivorous animals that were valued by humans before the Great War for their companionship and ability to hunt vermin, such as rodents, snakes, scorpions, and other household pests.
After the Great War, many cats in what used to be the United States were hunted for food because they were an easy prey. Although not as common as before the Great War, domestic cats still survive as witnessed in the Commonwealth. Domestic cats are something of a luxury item; Stacy noted that her late mother kept a close guard on their cat. A woman in Broken Hills also noted feeding their cat.
Some cats were possibly thrown into FEV vats by the Master in the Mariposa Military Base and by the Vault-Tec scientists in Vault 87, together with humans, dogs and other animals. The misshapen centaurs are the result of this mix.

Mr. Pussy, a domestic cat, died in Carbon, Texas in 2208. Ruby the prostitute wanted to find him when he got lost, and asked the Initiate to help. They discovered the cat's corpse in the Carbon Crater and brought it back to Ruby.
According to the Nursery design document, various cats were to make an appearance there. There would have been friendly domestic cats kept by humans, as well as wildcats, bobcats and panthers that were hostile to the player.
- If you use the perk Animal Friend on a cat and attack or get caught stealing from a settlement, all settlers will attack the cat as though it is a threat, though it is not combat-enabled.
- With the Wasteland Workshop add-on, a cat can be captured in any settlement via a cat cage. Once released, it will add 10 bonus happiness points to the settlement (as much as some tier 1-2 stores). A beta wave emitter is not necessary to tame them. Also unlike all other captures, cats captured this way are protected.
