- The Pet Health Library contains information on some of the most common medical problems of dogs and cats. This information is designed to assist pet owners in better understanding their pets' health problems.
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.
