Guinea pigs are tameable herbivores with a fast movement speed. Guinea Pigs come in three colors: Cream, Black and Brown.


Guinea pigs can be found in temperate forests, temperate swamps, tropical rainforests, tropical swamps, arid shrublands, deserts, extreme deserts, and cold bogs. They can either be tamed by a handler or self-tame in a random event.

Guinea Pigs can be bought and sold in other faction bases and from bulk goods traders. Guinea Pigs purchased from traders will be already tamed.


Guinea pigs can be farmed for meat and fur. While each guinea pig is small, they reproduce rapidly, so a large pack of guinea pigs can produce a lot of material. Compared to chinchillas, guinea pigs are not pen animals, so they will need to constantly be re-tamed. However, guinea pigs can nuzzle and can be controlled via allowed areas.

Due to their high reproductive rate, guinea pigs can be used as bait animals. Set an allowed area towards the direction of raiders. This allows you to direct where the guinea pigs go, and they will be shot at rather than your colonists. This results in less meat & leather than slaughtering them would, but can be useful in combat. Compared to rats and hares, guinea pigs offer a more valuable fur and can nuzzle colonists, but are larger targets and reproduce less.

They are one of the few animals that can nuzzle, occasionally giving a +4 Nuzzled moodlet to colonists. Guinea pigs and monkeys are the only 2 wild animals that can nuzzle.


Guinea pigs have valuable fur. As clothing and building material, it has a few merits, but is generally lacking:

  • Guinea pig fur may not have the best physical protection, but it has the best cold insulation in the game, protecting your colonists against cold temperatures. Guinea pig parkas are the most insulative gear in the game. In less extreme biomes, tribalwear can be used to protect against heat and cold, potentially letting you wear a jacket instead of a parka. However, guinea pigs are only native to tropical biomes, which ultimately limits this use.
  • Guinea pig fur is very beautiful. However, only a select few objects can be made out of leather - a single armchair's beauty is unlikely to have much impact.

Otherwise, the best use for their fur is for trade. It is a valuable resource, worth more than even devilstrand.

Female guinea pigs produce:

  • Baby slaughter: Guinea pig fur 1.05 fur per day, or Guinea pig fur 6.569 fur per 1 unit nutrition.
  • Adult slaughter: Guinea pig fur 4.2 fur per day, or Guinea pig fur 10.357 fur per 1 unit nutrition.

When considering a 1:1 ratio of males:females, fur lowers to Guinea pig fur3.285 per 1 unit nutrition (baby), or Guinea pig fur 7.429 per 1 unit nutrition (adult). A higher ratio of females will increase efficiency from there.

For the sole purpose of farming leather, chinchillas are superior as they do not need to be retamed. Guinea pigs have some non-leather advantages, as listed above.

*As of version 1.1.2610, all animals can be tamed. The percentage of likelihood of success depends on factors such as the Animals Wildness Percentage, Pawn Handling Skill, and others. More information can be found on the animals page.

  1. Coverage determines the chance to hit this body part. It refers to the percentage of the super-part that this part covers, before its own sub-parts claim their own percentage. For example, if the base coverage of the super-part is 100%, and the coverage of the part is 20%, 20% of hits would hit the part, and 80% the super-part. If the part had its own sub-part with 50% coverage, the chances would be 10% sub-part, 10% part, 80% super part.
  2. Target Chance is the actual chance for each part to be be selected as the target when each part's coverage has been taken into account(I.E. Neck covers 7.5% of Torso but Head covers 80% of Neck so it actually has only a 1.5% chance to be selected). This is not pure hit chance, as different damage types propagate damage in different ways. See that page for details.
  3. Note that capacities can affect other capacities in turn. Only the primary effect is listed. See specific pages for details.
  4. This is the part that everything else connects to to be considered 'connected'.
  5. If Moving drops below 16% a pawn cannot move.
  6. A Scratch attack that varies from animal to animal. Each front paw allows one attack.
