A player's hellcat in battle with the rat king.

The king rat is the last surviving rat in the warehouse in south-east Varrock after players poison the other rats during the Ratcatchers quest.

It can only be fought by the player's kitten or cat. If the player asks their cat to be cautious, the cat will flee when half its hitpoints are left. If not, the cat will automatically retreat if it has only one hitpoint remaining, forcing you to restart from the beginning of the fight.

Combat stats

Strategy

  • The king rat has 10 Hitpoints and can only hit cats for 1 damage. However, it can hit fairly accurately, and the damage adds up. The cat may also have low Hitpoints if it is not fully grown.
  • Players can use raw or cooked fish on the hole in the wall (not on the cat itself) to heal their cat. If the cat is still a kitten, it is recommended that players bring a full inventory of fish for the fight. Raw karambwanji can also be used as a stackable form of food for your cat.
  • Overgrown cats can be used for this fight.

(Update)

Cats will now run away when they reach 1 HP in their fight against the King rat, rather than fighting to the death.

Trivia

  • The king rat had a festive override wearing a red partyhat during the 2017, 2018, and 2019 Christmas events.
