Cat Lane, Dip. CFN,  Chartered Herbalist

Since 2001 I have worked with close to five thousand cases, averaging around 300  full service cases per year., an intensive diet and herbal consultation that involves the development of several recipes and herbal protocols with online support during transition, and follow up to ensure the protocols are successful.  In addition I do online and in-person herbal consults  of a more straightforward nature, which do not involve as much time as the intensive option, on average another 3-400 per year. This includes proactive diets for healthy adult dogs; growth and senior diets; specialized dietary care for  conditions including but not limited to cancer, allergy, IBD, liver disease, kidney disease, uroliths (oxalate, urate and struvite stones) osteo-arthritis, various forms of heart disease, Cushing’s disease, Addison’s disease, diabetes, pancreatitis and obesity, as well as specialized diets for performance dogs.

I have never met someone more dedicated to ensuring that dogs live happy, healthy lives than Cat Lane, As a fellow herbalist, I have long admired her depth of knowledge, her original thinking, and her dedication to constantly learning and honing her craft. On a more personal level, her knowledge, insight, and intuition were a tremendous help in ensuring that my Siberian Husky lived a long and rich life, and her compassion and generosity inspire me.. I consider her the foremost canine herbalist and nutritionist in North America and recommend her highly.

“As the population of self-made gurus and “certified” shamans continues to grow, it is increasingly difficult to find solid, holistic advice from someone who truly who “walks the walk” and doesn’t simply “talk the talk.” Fortunately, we have Catherine Lane, a “real deal” canine nutritionist who is not only highly trained and experienced in nutrition and herbal medicine, but who brings forward a real-life, truly holistic perspective in all that she does. Her work looks well-beyond the symptoms of disease to address the true nature of each individual dog she works with, and best of all— she works from the heart.”

“Cat Lane has both an inborn gift with animals, as well as learned wisdom and skill gathered over decades as a clinician with a passionate calling to heal all creatures great and small. Her knowledge of herbal medicine is obvious in her work, as well as her deep love for the animals. Cat is the very first person I look to if I have questions about what might most help an animal friend, and I have the utmost respect for her experience and understanding.“

“Cat Lane is the most experienced expert I know when it comes to nutrition and herbal medicine for dogs. I am personally an avid rescuer of abused dogs in need of forever homes. I am also a professional, clinical herbalist and teacher with over 30 years of experience working with plant medicine. However, if I have a question regarding herbal medicine when it comes to dogs, Cat Lane is always the person I turn to. With her, it is so wonderful to have such a generous resource of information based on real-world animal-care experience using herbs and nutrition.”

From my interactions with Cat Lane in various forums, she shines as an expert in herbal and nutritional care for animals. If you have an animal with health issues, Cat will be a great help to you and your companion.

“Cat’s approach is just the perfect combination of science, herbalism and nutrition. For too long the disciplines have been isolated from each other. Cat’s skill in combining the fields gives me faith that at some point there will be better cooperation between the veterinary field and more holistic and nutritional approaches.”

Charley Gray, DVM

The Raw Vet

“As a veterinarian, I appreciate Cat’s scientific approach to nutrition. Her recipes and recommendations are based on research, not opinion and fad. I know when I send a client to her for a consult, they will get the support and the follow up needed to be successful using food and herbs to improve their dog’s health.”

Heather O’Leary DVM CVA CVSMT

Tessaloo Veterinary Services PLLC

“I recently needed a lot of help with my dog Gary who was having a hard time digesting his food.  He was also recovering from a recent life saving surgery. Cat took the time to research his health issues and worked with me to give me the best recipe that could possibly help our little guy.  Well, fast forward 4 months and you wouldn’t recognize him.  He has finally put on a much needed 2 kg and regained his strength back.  Thank you Cat for your wonderful work!”
