Fallout Shelter pets

Pets are domesticated small animals, cats and dogs, that confer a bonus effect on the dweller to which they are assigned. Assigned pets can be used either inside the vault or outside in the wasteland. One pet may be assigned to each single unpaired room, with two pets the maximum for double rooms and three for triple paired rooms. Pets can be found in common form, with generic breed names, rare form with generic names or uniquely named legendary form. The rarer the pet, the greater the bonus it confers, but even identical pets may confer bonuses with slightly different strengths. Pets can be found in lunchboxes and pet carriers and are assigned to dwellers in a similar fashion as weapons and clothing.
