The Sims 4: Cats and Dogs expansion pack introduces pets as fully interactive members of the household. Released on November 10, 2017, the pack allows players to create and care for cats and dogs, build relationships with their pets, and even run a veterinary clinic.

With a new coastal world, animal-focused careers, and detailed pet customization, Cats and Dogs adds one of the most beloved gameplay features in The Sims 4.

The New World: Brindleton Bay

Cats and Dogs introduces a coastal town called Brindleton Bay, inspired by seaside communities. The world features scenic beaches, harbors, and parks where Sims and their pets can explore together.

Brindleton Bay includes several neighborhoods with different styles and environments.

Sable Square
A historic town center with traditional architecture and community spaces.

Cavalier Cove
A quiet residential area perfect for families and pet-friendly homes.

Deadgrass Isle
A mysterious island location surrounded by fog and old ruins.

Whiskerman’s Wharf
A waterfront district filled with docks, seafood restaurants, and fishing spots.

These locations offer plenty of opportunities for pets and Sims to interact with the environment.

Create-A-Pet Customization

One of the most detailed features of the pack is Create-A-Pet, a system that allows players to design cats and dogs with extensive customization.

Players can adjust many aspects of their pets, including:
  • Breed and body shape
  • Fur length and color patterns
  • Eye color and facial features

Personality traits

The pack includes many real-world dog and cat breeds, but players can also mix traits and appearances to create unique pets.

Pets can be playful, friendly, independent, or mischievous depending on the traits selected.

Pet Personalities and Behavior

Each pet has a unique personality that influences how it behaves in the household.

For example:
  • Friendly pets enjoy interacting with Sims and other animals.
  • Playful pets often seek attention and enjoy toys.
  • Independent pets prefer exploring on their own.
  • Curious pets investigate objects around the home.

These personality traits make each pet feel different and add realism to household dynamics.

Pets may also develop habits over time, such as sleeping in specific locations or playing with certain objects.

Caring for Pets

Sims must take care of their pets’ needs to keep them healthy and happy.

Basic pet care includes:
  • Feeding pets regularly
  • Playing with them for exercise and fun
  • Training dogs to follow commands
  • Giving pets affection and attention

Pets may also become sick occasionally, requiring treatment at a veterinary clinic.

Taking good care of pets strengthens the bond between Sims and their animals.

Training Dogs

Dogs in the game can be trained to perform commands and develop good behavior.

Training options include teaching dogs to:
  • Sit
  • Stay
  • Roll over
  • Fetch objects

Well-trained dogs behave better in the household and respond to their owners more effectively.

Training sessions also strengthen the relationship between the Sim and the dog.

Running a Veterinary Clinic

Cats and Dogs introduces the Veterinarian skill and allows Sims to run their own veterinary clinic.

At a vet clinic, Sims can:
  • Examine sick pets
  • Diagnose illnesses
  • Perform treatments
  • Manage clinic staff

Running a clinic requires balancing business management with animal care.

As the clinic gains reputation, more customers will visit for pet treatment.

Pet Illness and Treatment

Pets may occasionally become sick, showing symptoms such as unusual behavior or discomfort.

Sims can bring their pets to a veterinary clinic to receive treatment.

The veterinarian must diagnose the problem and apply the correct treatment using medical equipment or medication.

Proper care helps pets recover quickly and return to normal activities.

Stray Animals

Brindleton Bay includes stray cats and dogs that wander around the town.

Sims can interact with these animals by:
  • Feeding them
  • Petting them
  • Building relationships

In some cases, Sims may even choose to adopt a stray pet and bring it into their household.

This feature adds realism to the world and encourages compassionate gameplay.

Build Mode and Pet-Friendly Homes

Cats and Dogs introduces many Build Mode items designed specifically for homes with pets.

Examples include:
  • Pet beds
  • Food bowls
  • Litter boxes
  • Pet toys
  • Veterinary equipment

Players can design pet-friendly spaces where animals can sleep, eat, and play comfortably.

These items help create homes that feel designed around both Sims and their pets.

Create-a-Sim Clothing

The pack also includes clothing inspired by coastal living and casual lifestyles.

Create-a-Sim items include:
  • Comfortable sweaters
  • Casual jackets
  • Relaxed outdoor clothing
  • Practical everyday outfits

These clothing styles match the seaside atmosphere of Brindleton Bay.

Storytelling Opportunities

Cats and Dogs opens many storytelling possibilities centered around pets and animal care.

Players might create stories about:
  • A family adopting their first pet
  • A veterinarian building a successful animal clinic
  • A Sim rescuing stray animals
  • A pet owner training dogs for competitions

Pets add emotional depth to households and make family gameplay more meaningful.
