Cat Friendly Practice

In the United States, there are millions more owned cats than owned dogs, yet cats visit veterinarians less frequently than dogs. A major reason is that it is very stressful to take cats to the veterinary practice and often owners believe their cat doesn't need routine check-ups for wellness and preventive care. The Cat Friendly Practice® (CFP) program, created by expert feline practitioners, provides a solution to this trend and provides an opportunity for veterinary practices to elevate care for cats and reduce the stress during the visit.
