Founded in 1975 by the late Dr. Barbara Stein, a pioneer in veterinary medicine and one of four women in her graduating class, Chicago Cat Clinic focuses solely on feline veterinary care. We are proud to be part of the legacy that helped transform the way leading doctors feel about feline specific practices. In previous years, cats were treated as small dogs. Dr. Stein traveled across the globe and within the U.S. lecturing to fellow veterinarians about the tremendous differences between cats and dogs.
