Pets are character modifiers that last between 11 and 16 years and can be inherited if a character dies before the pet. Both pet modifiers unlock a  Decision to pet them and have a hidden 33% chance to save the character when a Murder Scheme is executed against him or her. There are two pet modifiers:

  • Modifier dog positive.png Pet Dog grants +1 to  Diplomacy and  Prowess
  • Modifier cat positive.png Pet Cat grants +1 to  Intrigue and  Learning

Both pet modifiers can be obtained in two ways. One day after getting the modifier the character will be given the option to input a name for the pet.

  • At any point the character may be given a pet from a consort, friend, lover or vassal and gain the option to keep it or sell it for a minor random amount of  Gold.
  • During childhood the character might encounter a pet and have the option to keep it and gain the modifier. Alternatively if the character has the Trait sadistic.png Sadistic trait it can kill the pet to gain +1  Learning.

While the character has a pet modifier the following events can take place:

  • A vassal plays with the pet and gains +20  Opinion
  • The pet brings 2  Gold
  • The pet gives a temporary  Health Boost
  • The pet ruins a vassal's possessions, bringing the following options:
    • Pay the vassal and lose a moderate random amount of  Gold
    • Lose -20  Opinion with the vassal
  • If there is a scheme targeting the character there is a very small chance for the pet to expose it.
  • If the character has both pet modifiers it might gain an event that grants -20 Stress
  • If the character has both pet modifiers the two pets might fight. Within two weeks one on the following will happen:
    • 30% chance the dog dies
    • 45% chance the cat dies
    • 15% chance both die
    • 10% chance they get along and the character gains -10 Stress
