New features[]

World and neighborhoods[]

The Sims 4: Cats & Dogs includes Brindleton Bay, a brand new world that is based on typical New England seafront towns.

Cats and dogs[]

Main articles: Cat and Dog

In Cats & Dogs, Sims can own cats and dogs as pets, which is the main feature of the expansion pack. Unlike previous games, pets cannot be controlled by the player, similar to The Sims 2: Pets, no cheat will allow the player to do so. Sims can interact with these pets in various form of ways such as feeding, playing, and training, and can bond with them through these interactions.

Both pets have three life stages; kitten/puppy, adult, and elder. They will live through these life stages like normal Sims, but much shorter. Pets can also die, but only from old age. Both cats and dogs can have three different pet traits, which are unique to them and are not available to Sims. These traits control the pets' actions and reactions toward the surrounding world. Some traits have unique attributes for one of the two species, but most traits are identical to one another. After the pet ages into an elderly cat/dog, they will live for an additional 6 to 11 Sim days before dying of old age.

Cats and dogs can be created with Create a Pet, and there are many pre-made breeds for them. Players will be able to customize their pets' appearance and even make their breeds. Create a Pet borrows the same click-and-drag mechanic from Create a Sim, making players able to sculpt and mold their pets to have more details and features.

Vet clinics[]

Main article: Vet clinic

The Sims 4: Cats & Dogs also introduces a brand new feature to the series, which is vet clinics. They are a lot of types of businesses that Sims can own. Cats and dogs can now have various types of illnesses, that can be easily cured by veterinarians. They are treated with different types of medicine and in serious situations with a surgery station, that can also neuter and un-neuter pets.

Sims can now learn the veterinarian skill, which is essential to running a vet clinic. Vet clinics are handled similarly to restaurants from Dine Out, as customers have a rating system that determines the vet clinics' overall star rating. Pets are treated on exam tables and require some amount of research to diagnose the disease, before treating them with the appropriate medicine. The pets also have a stress bar to showcase to the player their current level of stress. Treating pets successfully can rise the overall rating of the clinic.

The following list shows how several existing packs integrate with The Sims 4: Cats & Dogs:

Realm of Magic

For Rent

  • Property owners of residential rentals can set a unit's rule with "No Pets" from their tenant agreement. Having tenants with pets present in their household unit will violate their tenant rule.
  • Tenants will partake the Pet Adoption Drive event, which stray pets will roam around the unit for tenants to pet them and have opportunity to adopt pets inside the unit.


Cats & Dogs was priced at 39.99 USD and 29.99 GBP at launch, the same as the original pricing of an expansion pack for The Sims 3. Expansion pack prices for The Sims 4 are intended to be similar to prices for The Sims 3 expansion packs in most locations.


  • With Cats & Dogs, players can create foxes and raccoons in Create a Pet. They are considered breeds for dogs and cats, respectively, but with optional different voices.[2] Foxes later appeared as NPCs in Cottage Living.
  • Contrary to all previous pet-themed expansion packs, Cats & Dogs did not include small pets. Rodents and hedgehogs were later included in The Sims 4: My First Pet Stuff.
  • Brindleton Bay has a premade same-sex couple, the Hecking family.
  • Unlike The Sims 3: Pets, pets are not controllable and unlike The Sims 2: Pets, there is no cheat to make them controllable.
    • However, there is a mod that can make them controllable and see their needs and family trees. Albeit in an incomplete state (most moodlets and traits lack icons or text while many interactions have duplicated names).
    • This mod only changes a few lines of code, showing that at one point pets were planned to be controllable by the player or were used for debugging purposes.
  • The Sims 4: Cats & Dogs is the only expansion pack which was released physically for console in Australia. It was bundled with the base game for PS4 and Xbox One and released on a single disc combining the two games together.
