At the Worcester Cat Hospital and Bird Clinic, we understand bringing your cat to the vet can be stressful for you and your feline friend. Since we cater to felines (sorry, no canines here), we find our patients to be generally calmer and at ease in our cat only atmosphere.

In mixed practice clinics, cats are often seen and treated as small dogs. Since we are able to concentrate on cats, our knowledge and procedures are state of the art for felines – whether treating the feline diabetic, geriatric patient with diseases like thyroid and kidney disease, or helping our clients with the basics on caring for their new kitten.

We have many cats with special needs board with us to ensure their medications and problems are carefully monitored when their families travel. Bringing your feline friend to our hospital means giving them the care and expertise only a Cat Hospital can provide.


Owner/DVM Nancy O’Leary received her Doctorate in Veterinary Medicine in 1992. Since 1994 Dr. O’Leary’s concentration has been exclusively on Feline and Exotic medicine and surgery. Dr. O’Leary is board certified in Veterinary Acupuncture, and Chinese Herbal Medicine and has authored a chapter in the premier textbook and reference for Reptile Medicine by Dr. Douglas Mader.

The staff at the Worcester Cat Hospital and Bird Clinic bring twenty plus years of experience to care for your pet’s needs. Four of our six staff members have been with our hospital for more than seven years. All of our technical staff have college degrees and our full time technical staff are certified veterinary technicians. Our staff truly dedicate themselves to your feline and exotic family members by providing them with the care they need and assuring their caregivers have all the tools and information needed to keep them healthy.

Birds and Exotics

Approximately fifty percent of the caseload at the Worcester Cat Hospital and Bird Clinic is comprised of exotic pets. As a long standing AAV member (the veterinary organization dedicated to Avian and exotic species) Dr. O’Leary has attended hundereds of hours of continuing education for avian and exotic animal medicine and surgery.

She is a published author for a Reptile Medicine text and is part of a veterinary network through VIN (Veterinary Information Network), where a panel of Specialists are able to share and discuss the problems and issues of Avian and Exotic species with fellow experts in the field.

Each staff member at the Worcester Cat Hospital and Bird Clinic is thoroughly trained in the diets, husbandry (general care), needs and problems of the various species we see, in order that you, our client, has the resources you need to properly care for your special pet. Snake or lizard, guniea pig, hedgehog, budgie or macaw…we see them all.


The Worcester Cat Hospital and Bird Clinic is dedicated in their efforts in providing their clients with all of the tools and information needed to give their Cats and Exotic Pets the best possible care.

  • We offer extended exam times without extra fees to be sure our clients questions are answered and all of their needs are met.
  • We have created information packets for the varied species we see so that our clients have a handy reference to use after leaving our clinic.
  • We also provide information sheets on specific diseases or conditions to aid our clients in understanding the problems and treatments their pets may have.
  • When an extended stay for a medical problem or surgery occurs, we provide thorough discharge instructions to assure proper care and recovery for your special companion.

We want you to understand your pets’ needs and feel enabled in their care both when they are ill and when they are well.
