Specialized Care


“Dr. Rubenstein and the staff at A Cat Clinic know their stuff. And I’m not just saying that to be nice, my owner agrees. No matter how big or small the issue, they always find answers and address our concerns. Specialized care is more than just words, Dr. Rubenstein is among the best-of-the-best in the country when it comes to feline medicine. She and her staff are committed to offering the best care for me and the best information about preventative care and treatment recommendations for my owner. I can’t say that I always look forward to my visits, but once I get past the nervousness I know I’m in the best hands when I arrive.”

- Mr. Cat


Dr. Dale Rubenstein

Dr. Rubenstein opened the doors of A Cat Clinic, the first all-feline veterinary practice in Montgomery County, in 1986. Not long into her professional career, Dr. Rubenstein worked for an all-feline practice in Virginia and immediately knew it was for her. The experience reinforced what a professor once told her, that cats are tough patients because they hate being sick.

A Montgomery County native, Dr. Rubenstein earned her BA in Biology from Oberlin College, her MS in Nutritional Biochemistry from the University of Maryland and her DVM from Purdue University School of Veterinary Medicine. She became board certified in feline practice, one of only 80 diplomats in the U.S., through the American Board of Veterinary Practices (ABVP) in 1996 and re-certified in 2006. Dr. Rubenstein is also a member of the American Association of Feline Practitioners (AAFP), American Veterinary Medical Association (AVMA), Maryland Veterinary Medical Association (MVMA), Cornell Feline Health Center, Montgomery County Humane Society Feline Focus Committee, Montgomery County Veterinary Medicine Association, as well as a member of the credentialing committee of the American Board of Veterinary Practitioners (ABVP).

Dr. Rubenstein feels very fortunate to be able to work with our wonderful clients who take an interest in the long-term well-being of their cats. A veterinarian of almost 30 years, Dr. Rubenstein is dedicated to making sick cats better and keeping healthy cats well as long as possible (A Cat Clinic’s record holders are 26 years old). Her special interest is in senior kitties’ (geriatric) internal medicine, but when a client gets a new cat she’s always delighted to welcome a new addition.

When she’s not caring for her patients, Dr. Rubenstein can be found at home with her husband, daughter and son – and her three cats, Minnie, Eva and Athena.

“At A Cat Clinic, we understand cats’ sensitivities to change, which is why we’ve created a low-stress environment dedicated to the well being of our patients and clients. We are an extended family to our clients – we cheer the milestones of our patients and we mourn the losses. Personally, I truly enjoy working with our clients to promote healthy lifestyles for their cats. And when the time comes to treat an illness, I work directly with our clients to determine the best course of treatment for their cats. When a cat is entrusted to me I care for that cat as if it were my own, so much so that when it snows, I take the cats home with me!”

Upon moving to Maryland, Dr. Mullins worked in several different practices before finding A Cat Clinic, where she’s been ever since. She is also a member of the American Association of Feline Practitioners (AAFP), American Veterinary Medical Association (AVMA) and the Maryland Veterinary Medical Association (MVMA).

A cat lover, Dr. Mullins shares her home with her husband, two cats, Suvi and Kia, and her Saluki dog, Jasper.

Dr. Melissa Mustillo

Following graduation, she moved to Maryland and joined the staff of VCA Veterinary Referral Associates to complete the hospital's intense one year internship program.
