Rodents are a group of small pets. They were first introduced in The Sims: Livin' Large and reappeared in The Sims 2: Pets, The Sims 3: Pets and The Sims 4: My First Pet Stuff.
The Sims: Livin' Large[]
In Livin' Large, the guinea pig was introduced. If the cage wasn't cleaned for a long time, and it bit a Sim, the Sim would become sick. The fastest and easiest way of curing this sickness is to buy the guinea pig painting and look at it.

The Sims 2: Apartment Pets[]
In The Sims 2: Apartment Pets, Richard the hamster and Smudge the guinea pig are a couple of the pets located in the Sim's apartment. The player can buy toys for them, play with them, and dress them up. They do not need to be fed and never die.
The Sims 3: Pets[]

Rodents are one of the various kinds of minor pets introduced in The Sims 3: Pets. They can be caught outdoors like other collectibles. Rodents can be kept temporarily in the inventory, but they might eventually run away if kept for too long. Rodents need to be placed in terrarium and be fed regularly.
Being a collectible pet, there is no limit to the amount of rodents a Sim can collect.

List of rodents[]
Although they are referred to as rodents in-game, shrews and hedgehogs are not actually rodents.
The Sims 3: Pets introduces 7 Rodent types. Each has its own rarity and worth.
There are only 3 common rodent available via the "Stock a Terrarium" option. The rest must be caught in the wild.

In addition to the regular rats found in Pets, another breed of rats are found in the rarely encountered squatter lot challenge, where they cannot be interacted with other than to shoo them away.
The Sims 4: My First Pet Stuff[]
The Sims 4: My First Pet Stuff adds four new rodents in special cages. Unlike cats and dogs, rodents do not have life stages. However, they can still die of old age or starvation. When a rodent has passed away, a notification will appear, and the rodent's "soul" can be seen leaving the cage.
Sims can buy the Feat Anti-Aging Treat (§300) to halt their aging. The treat can be purchased on the computer or vet clinic.

Hamster | §400 | Stomp your feet and clap your hands, c’mon, everybody, it’s the hams… *record scratch* “…shhh; they must never find out about the dance! Back to plotting our escape!” |

Pygmy Hedgehog | §500 | Perhaps you have a prickly personality… if so, the Pygmy Hedgehog may be the right pet for you. Before hedgehogs came into existence, they lived in the ocean as the creature we call sea urchins. While there’s still disagreement over what caused this critter to grow legs and walk onto land, acknowledging that they make fantastic pets is settled science! |

Rat | §600 | San Myshuno! It’s a wonderful town, well… except for its infamous rat infestation. Running through the sewers, crawling through apartment building walls; they’re everywhere! What’s a mayor to do? Thankfully, there’s nothing a little political spin can’t fix… Can I interest you in a pet rat? How about two? |

Bubalus | §700 | After a talking plush of Bubalus became the best-selling toy of 2016, pet breeders saw an opportunity they were uniquely qualified to seize upon. Using genetic engineering, they’ve taken the body of a Hippopotamus, the color and spiral shape of a Violet Sea Snail, and the fur, size, and disposition of a Hamster, to create a new species of animal dubbed the Dwarf Bubalus. Now you can have one of these once fictional creatures to call your very own! |
Cage[]
There is maximum one rodent per cage. As long everything is available in their cages, rodents would be able to stay healthy. When a rodent cage is purchased, the new rodent will be well fed. Sims need to refill the food bowls and clean the cage regularly.
The following interactions are available on rodent enclosures:
- Clean Habitat
- Fill Food
- Feed Treat
- Observe
- Play With
- Purchase Rodent
- Release
- Rename
- Study Rodent (Child/Teens Only)
- Talk
- Investigate and React (Cats and Dogs) (Require The Sims 4: Cats and Dogs)
The cage has a corkboard that allows Sims to pin postcards on.
Rodent travels[]
Rodents in The Sims 4: My First Pet Stuff can travel to far away lands. They sometimes leave their cage, and bring back a postcard from where they travelled to. A note can be seen in the cage, notifying they have left the cage. If Sims do not want their rodent to go on adventures, they can purchase the IQ limiter vet treat (§350) which will set their IQ to a normal level.
Notifications will inform the adventures along the way.
Rodent Fever[]
If a rodent's terrarium gets dirty, rodents may contract Rabid Rodent Fever. Sims who play with these animals can be bitten, resulting in a "Bite-Sized Bite" moodlet that lasts for two hours. A Sim is more likely to be bitten if he or she has a poor relationship with the rodent they are playing with. After two hours, the moodlet will either expire or turn into the "Fuzzy Feeling" moodlet that lasts for an additional 24 hours. Each subsequent stage of the disease lasts 24 hours: Sims will get the "Fuzzy Fever" moodlet in the next stage, where the disease becomes contagious to other Sims, and will transition to the "Rabid Rodent Fever" moodlet in the final stage of the disease. They will die of the disease after this moodlet expires. Their ghost will appear as an oversized hamster foaming at the mouth.
At all stages of the disease, Sims can cure themselves either by buying rodent remedies using a computer or asking about the fever at the local vet clinic. Ghosts can drink the serum[which?] to cure foaming and transform back to human form.[confirmation needed]
