We Understand Cats

Our Mission: Saving the World One Cat at a Time!

Boulder Cat Vet watches over the Health of your Feline


Unique and awe-inspiring creatures, they grace us by accepting us into their lives and allowing us the privilege of caring for them.  

“Cats Are Not Small Dogs.”

Cats are a unique species with unique medical needs. Effective feline healthcare must be based on understanding that uniqueness. As dedicated feline-exclusive professionals, our knowledge of feline-specific health and medicine informs everything we do for you and your cat.

Cats Are Our Passion

The Feline Healthcare Team at the Uniquely Cats Veterinary Center is motivated by a deep passion for cats — for helping cats to live healthy lives, for helping sick cats to get better, for nurturing the human-feline bond, and for sharing our knowledge and the joy of feline health and happiness.  We are dedicated to providing the most thorough, compassionate and advanced care to each individual cat entrusted to our care.

Feline-Specific Care

Our cat care, whether provided in the feline-friendly, homelike environment of our brand-new state-of-the-art hospital or in your home, emphasizes disease prevention through species-appropriate nutrition, wellness care, risk-based vaccination plans, environmental enrichment and stress management.  We are expert in the diagnosis and compassionate treatment of feline disorders.Feline Veterinarians here to help your cat

Every Cat Is Unique

We understand that every cat, cat parent, and cat home dynamic is unique. Our doctors and staff will work with you as a team to find the most effective path, for you and your cat, to good health and a happy life together.

Experience Matters

Our Founder and Medical Director, Dr. Fern Slack, brings over 20 years of experience of feline-only veterinary care and a deep and abiding love of cats to the Uniquely Cats Veterinary Center.

Introduction to Uniquely Cats by Dr. Fern


Stuff Cat Parents Want To Know

Dr. Fern’s philosophy to cat medicine starts with one simple truth: “Education is the first line of defense for our feline friends.”  As you get to know the cat vets at Uniquely Cats Veterinary Center you will see that there is a difference in the approach taken from that of corporate and institutional medicine.  Each cat and their human have a unique relationship. It is our goal to help you better understand that relationship and in turn provide you with a better understanding of your feline friend.

We will continue to publish new articles to help you become a better cat parent. Remember you have been entrusted with the care and well being of your more transient feline friend. Your education will help extend their temporal journey through your life.

Why Your Cat’s Dental Care Is Important

It can feel rather unlikely that your cat, who is eating and acting apparently normally, could be experiencing constant oral pain – yet it happens all the time, and cats hide it very well.  One way we know this is what we see happen after dental problems are addressed.

Cats Are Not Small Dogs

Cats are not small dogs. Unlike dogs, cats are obligate carnivores . They differ in dietary and habitat needs, organ function, behavior and more. Feline Health depends on veterinarians that understand the truly unique nature of cats.

Boulder cat parents, you are so fortunate!

Dr. Slack is an exceptionally gifted veterinarian…


Dr. Slack is a brilliant diagnostician…

I found my dream veterinarian for my cat!

I want to recommend Dr. Fern Slack of Uniquely Cats Veterinary Center. Dr. Slack has 20+ years of feline-only veterinary care and understands how to treat cats (hint: not like dogs!) She is truly “wholistic,” like a functional medicine doctor for your cat. She knows what tests to run and how to interpret them, she looks at any stress in the home, and she understands the importance of an appropriate diet (hint: not dry food!) to maintain health. She’s been very generous with her time with me and my older cat. Her center opens in July and is currently doing home visits. Oh, and she’s VERY reasonably priced for the quality of care she provides!

I have been totally moved by Fern’s commitment to, and passion for, her four-footed patients

She speaks with the authority and expertise accumulated from nearly 25 years of exclusively feline experience, yet with an understanding and sensitivity that immediately inspire trust and confidence…


In my years of living with animal companions and interacting with veterinarians, I have never had the privilege of encountering such an exceptional veterinarian…

State-of-the-Art Feline Veterinary Hospital

The Uniquely Cats Veterinary Center is now open in the heart of Boulder, CO. We are now seeing patients in the new cat hospital. We still have some decorating and spiffing up to do, but look how far we have come!

We have a sign!

Our location is in the REI/Marshall’s plaza next to Hazels.

An Empty Shell

The Indian Restaurant is now gone.

Framing Starts

The skeleton of metal starts to grow.

Dental Suite Takes Shape

Our State-of-the-Art dental suite is taking shape!  Just weeks away from opening now.

Days Away Now

Just days away from moving into the hospital.  There’s still some cleaning and punch list items, but you can now see it coming together.

Reception and Cat Adoption

We are loving the look that Rodwin Architecture and the Uniquely Cats team created for our reception.  It’s going to be a beautiful and peaceful space for you and kitty face.

It will be especially nice once the ladder and blue blankets are gone 🙂
