The path to veterinarian in The Sims 4 starts with the Animal Enthusiast aspiration and the Friend of the Animals trait

To become a veterinarian in The Sims 4, your Sim needs to reach level 10 of the Veterinarian career, which is available through the Cats & Dogs expansion pack. The career has two branches at level 4: Small Animal Veterinarian and Large Animal Veterinarian. You can switch between them once, so choose based on whether you want to treat household pets or work with larger animals like horses.

The fastest way to start is to have your Sim explore for the Veterinarian job directly from the computer or phone once they reach Young Adult age. However, building the right skills and traits beforehand makes the climb to level 10 much faster and less frustrating.

Key Takeaways

  • Your Sim must have the Veterinarian career from Cats & Dogs installed and reach Young Adult age before they can explore for the job.
  • The Veterinary Science skill is the primary skill that determines job performance and promotion speed—train it before or when ready after starting the career.
  • The Animal Enthusiast aspiration and Friend of the Animals trait give your Sim a head start in building relationships with animals and performing better at work.
  • You can switch career branches once at level 4, so test both Small Animal and Large Animal paths before committing to one for the final stretch to level 10.

Build the Veterinary Science skill before explore

The Veterinary Science skill is what your Sim will use at work every day. The higher the skill level when you start the job, the better your Sim performs during shifts and the faster promotions come. You can start building this skill as a Teen, which gives you a head start before your Sim becomes a Young Adult and can explore for the career.

To train Veterinary Science, have your Sim read the Veterinary Science skill books (available at the bookstore or library), or interact with animals directly. Petting, playing with, and caring for cats and dogs in your household builds the skill naturally. If you want to speed this up, use cheats or mods, but the skill books alone will get you to level 3 or 4 before you start the job.

Choose the right aspiration and trait for faster progress

The Animal Enthusiast aspiration is designed specifically for Sims who work with animals. Completing the milestones of this aspiration (like petting animals, building friendships with them, and learning about them) gives your Sim rewards that make the veterinarian career easier. The final reward, Friend of the Creatures, boosts how quickly your Sim builds relationships with animals and improves their performance in animal-related tasks.

If you want to lock in a permanent boost, choose the Friend of the Animals trait as your Sim's reward trait. This trait makes animals like your Sim more, which translates to better interactions at work and smoother job tasks. You can also select the Cat Lover or Dog Lover traits if you know which branch you want to pursue, though these are less essential than Friend of the Animals.

Understand the two career branches and when to switch

At level 4 of the Veterinarian career, your Sim must choose between the Small Animal Veterinarian branch (treating household pets like cats and dogs) and the Large Animal Veterinarian branch (treating horses and other large animals). Each branch has different tasks and different animals you will interact with, but both lead to level 10 and the same final title.

You can switch branches once during your career, so if you are unsure which you prefer, pick one and try it for a few levels. If you hate the tasks or the animals, you can switch at any point up to level 10. After you reach level 10, the branch you are on becomes permanent. Small Animal is generally faster if you already have cats or dogs in your household, because you can practice on them outside of work.

Perform well during work shifts to earn promotions

Once your Sim starts the job, they will attend work shifts where they perform veterinary tasks. The main task is diagnosing and treating animals that come to the clinic. Your Sim uses the Veterinary Science skill to examine animals, identify their problems, and provide treatment. The higher your skill level, the faster and more reliably your Sim completes these tasks.

During shifts, focus on completing tasks and building relationships with coworkers and the animals. Your job performance is tracked, and once the performance bar fills, your Sim is promoted to the next level. Shifts typically last four to six hours, so plan your Sim's day to include work, skill-building, and rest. Neglecting sleep or hygiene will tank your job performance, so keep your Sim's needs in the green before and after work.

Use the veterinary clinic lot to practice outside of work

The Veterinary Clinic lot (included with Cats & Dogs) is where your Sim works, but you can also visit it outside of work hours to practice. Bring your Sim's own pets to the clinic and have them examine and treat them. This builds the Veterinary Science skill without the pressure of a work shift and lets you experiment with different treatment options.

You can also adopt animals from the clinic or rescue them during work shifts. Having multiple animals in your household gives you more chances to practice the skill and build relationships, which makes work shifts smoother. Animals that already trust your Sim are easier to treat and require fewer interactions to complete tasks.

Manage your Sim's needs and work schedule

The Veterinarian career has shifts that vary in length and timing. Your Sim may work mornings, afternoons, or evenings depending on the day. Plan your Sim's schedule so they have time to sleep, eat, and maintain hygiene before work. A Sim with low energy or poor hygiene will perform poorly and may not get promoted even if they complete all their tasks.

Use days off to build the Veterinary Science skill, complete aspiration milestones, and build relationships with animals. If your Sim is struggling to keep up, reduce their workload by having them focus only on work and essential needs for a few days. Once they are promoted and the skill bar resets, they will find the next level easier.

Frequently Asked Questions

Can my Sim become a veterinarian without the Cats & Dogs expansion pack?

No. The Veterinarian career is exclusive to the Cats & Dogs expansion pack. Without it installed, the career will not appear in the job list and your Sim cannot pursue this path.

What is the fastest way to reach level 10?

Train the Veterinary Science skill to level 5 or 6 before starting the job, choose the Animal Enthusiast aspiration, and keep your Sim's needs high during work shifts. Completing work tasks and building relationships with animals will earn promotions faster than any other method.

Can I switch from Small Animal to Large Animal veterinarian after reaching level 10?

No. Once your Sim reaches level 10, the branch is locked. You can only switch once during the career, and only before reaching the final level. Plan your branch choice carefully or use a new Sim if you want to experience both paths.

Do I need to own animals to become a veterinarian?

You do not need to own animals to start the career, but owning them makes the job easier. Animals in your household let you practice the Veterinary Science skill outside of work and build relationships faster, which improves your job performance.

What happens if my Sim fails at work?

If your Sim performs poorly during shifts, they will not be promoted and may receive a warning. Poor performance is usually caused by low skill, low needs, or low relationships with coworkers. Fix these issues by training the skill, maintaining needs, and building friendships before the next shift.
