Rats are small animals that can be found in numerous locations, mostly in cities, sewers and dungeons. Thus, they are common animals found throughout RuneScape, typically Combat level 1 or 3.
Although most rats have no drops, the level 1 rats in the Stronghold of Security have a 100% chance to drop bones.
Considered by most players to be the weakest monster in the game, rats are frequently used to train Magic with Splashing. Rats possess only 2 Hitpoints, 8 total experience, 0 Defence, a max hit of 0, and Attack accuracy of 1. Rats are quite literally half as strong as chickens.
Rats respawn after a single game tick, the fastest respawn rate in the game. Rats appear in many dungeons and sewers throughout Gielinor, and due to their weakness and commonness, rats are not marked on the minimap. A similar critter, the level 1 spider, shares the same stats as the rat.
When clue scrolls were first introduced, rats had an extremely low chance of dropping an easy clue scroll. This was later changed so that rats never drop clue scrolls.
The rat was one of the first entities ever added to RuneScape, being the fifth behind Hans, goblins, men, and women. Its larger counterpart, the giant rat, soon followed.
Rats can be chased by cats. When telling a cat to chase vermin, it will pounce at a rat in range, attempting to catch it. If your cat successfully catches at least 100 rats, you can talk to Gertrude to get a Cat training medal, which has no special uses other than being a collectible. Furthermore, if you have a rat pole, up to six caught rats can be added to it as decoration.
Each type of cat has a different catch rate:
Hellcats share the same catch rates as regular cats, depending on their type.
The following drop rates are provided by Jagex, unless otherwise specified.
