Critters, also known as Pets, are passive immortal Mobs in Don't Starve Together, introduced in A New Reign. They look like baby versions of some other Mobs in the game and can be obtained from the Critters Tab while standing next to the Rock Den. Each pet requires two Items to adopt, an item related to the mob and a Crock Pot made food.
Critters will make noises when hungry but won't die if not fed. However, not feeding a Critter will cause its traits to decay faster. A Critter will get hungry after 2 to 4.25 days. A Critter can be "petted" by clicking on it, triggering a small animation. Feeding any Critter Glow Berries will make them have a temporary light radius.
Each player can only have one Critter at any given time. To get a different Critter, players must "Abandon" their current one by being near the Rock Den and right-clicking that Critter.
Critters can have traits which determine their behavior. Player actions add or subtract points from one of the Critter's traits, depending on the action, with the trait having the most points becoming the dominant trait and an adjective is shown in the Critter's name.
A Critter's first dominant trait is determined after 10 days of obtaining the Critter, and dominant traits are reassigned every 1.75 to 2.25 days.
Trait points decay at the rate of 1 point per day. The maximum amount of points a Critter's trait can have is 40, while the minimum is -12. Should all traits on a Critter have a negative point value, the Critter will revert to having no traits, and the next dominant trait is assigned after 3.75 to 4.25 days.
Performing an action that adds points to a trait that is already the dominant trait gives a 10% bonus to the points added to that trait.
The Combat trait adds the adjective "Scrappy" to the Critter's name and makes them perform aggressive animations towards monsters (but does not make them able to fight).
The Crafty trait adds the adjective "Crafty" to the Critter's name. It is currently the only trait that adds its name as the adjective.
The Playful trait is given to Critters when the player pets them and when they play (either by themselves or with other players' Critters).
The Playful trait adds the adjective "Peppy" to the Critter, increases the range at which they play with other Critters, and makes them play more often (effectively decreasing the rate of point decay, since playing adds points to this trait).
The Well-fed trait is given to Critters when the player feeds them. The points added to the trait are affected by the Food's freshness and its type and if it's the Critter's favorite food. Fresh food gives the full value, Stale food gives half (50%) of the value, and Spoiled food gives only a tenth (10%) of the value. All Crock Pot dishes give 4 points, while other food gives 1 point. The Critter's favorite food is the food item used in order to adopt it, and feeding a Critter its favorite food gives 5 points to this trait.
The Well-fed trait adds the adjective "Plump" to the Critter's name and makes them get hungry less often.
- Critters were added in the Cute Fuzzy Animals update, except for Giblets which were added with the Year of the Gobbler event.
- The Kittykit's name seems to be a mash up of the name for baby cats and baby racoons, "kitten" and "kit", as well as a play on the term "kitty cat".
- Despite their name, the Vargling's appearance is more similar to the Hound.
