The Advocat's (formerly known as The Nature of the Beast) specializes in the most humane, comprehensive and empathic approach to holistic pet care. The AdvoCat offers feline behavior consultations, humane education on understanding the needs of your pet for his/her entire life, and in-home hospice or critical care coaching for your pet. 

Shanti Zinzi is also an acupuncture consultant for a local veterinary practice and performs acupuncture on patients, too.  She utilizes Chinese medicine along with many integrated paradigms for biomedical and psychotherapeutic healing for her patients.

All aspects of your pet will be examined from distant medical & dietary history to current somatic & behavioral energetics, mental state, emotional stressors & psychological environment. Each pet will also be addressed for his/her unique constitution as well as age & breed propensities.

 With more than two decades in the animal business, The AdovCat's  priority is the health, happiness and well-being of your companion providing the most empathic care.

For our behavior clients, the most caring approach with gentle behavior modification that nurtures your pet is our priority. 



  • Shanti Zinzi is a great combination of scientific/medical knowledge and pure compassionate heart energy.  She is by far the best pet care person I have ever worked with, and I recommend her without reservation. She either has a solution or knows someone who does. Our big beast of a cat is completely in love with Shanti and purrs like a kitten when she is near (as opposed to eviscerating growls when vet type people come near). In sickness and in health, Shanti is our go to pet care guru.                                                                                                                                               Shayla from Abundant Health Detox Day Spa SF

  • Shanti Zinzi is a feline miracle healer. She is the reason my kitty is alive today ...Shanti was the miracle I was searching for. She is the reason my beloved Marina is still alive today. I still cannot fathom how this whole ordeal played out in ourfavor. She practically had stage 4 mast cell tumor and this was her third cancer   diagnosis!! Four years later and Marina is still in remission.. I'll never be able to thank her enough.                                                                                           Kristen Quinn Runway Model, Actress NYC, LA & Paris

  • Shanti Zinzi is the true unsung hero of animal advocacy and is affordable!  She will solve your pet problems and save you thousands in medical bill scams in the meantime.                                                Hida Viloria InterSex Society, US

  • Shanti helped me long distance with my two cats not getting along-she is veryattentive, and a very talented cat behaviorist.                                                                                                                                           Tony Morante from the NY Yankees

  • She also told me things about Tibby's kidney disease that no vet had told me before - for instance, that licking of lips? He's nauseous. I like my vet a lot but whyhadn't this been said to me, so that I could at least deal with that?  Shanthi toldme what meds to ask for, and the vet prescribed them immediately, unsurprised (this ticked me off a bit.) Shanthi also laid out my options for Tibby's death, which was clearly pretty close, in a gentle but practical manner, which is just what I needed. If your cat is sick, I would recommend Shanthi. If you simply want to keep your cat healthy, I would also recommend her. She's a font of wisdom; you'd be     surprised how little you know of cat care until she enlightens you.                                                        Caroline Paul acclaimed author and screen play writer

  • She doesn't simply tell you what to do, she brings you into the healing process.                                    Aldyth Beltane from All Creatures Healing Network

  • She is a brilliant investigator and feline behaviorist! Shanti solved my kitty's spraying problems at first home visit and checked in often to make sure all was well.                                                                               Kathy B. Mill Valley

  • The two treatments for my dog engendered such dramatic change. My dog was SO happy. Her spirits were light and free. I cherish those sunny end days in my memory always. All thanks to Shanti. She resurrected parts of my pet I thought forever lost to the cancer. Shanti said she specializes more with cats, but i don't believe it, my dog Violet acted like she was an old crony and nuzzled her for treatment.                          Anna Dokko SF

  • Amazing, a kitten thought to have FIP and very close to death, thriving after a few weeks of acute holistic treatment..                                                                                                                                                    Toni from Toni's Kitty Rescue/ TKR

  • I had the pleasure of hiring Shanti several times for holistic assistance with sickcats. The first was a foster cat in The Urban Cat Project. This particular cat had arrived to the rescue group from a central valley shelter near death. She literally brought back to life a cat who probably had 24 hours to live.  The second occasion I hired Shanti to come over daily and provide life-sustaining care for my own cat. Without Shanti's help, my cat would have had to be hospitalized at 10 times thecost and with a huge amount of stress. Shanti does a great job at healing the animals and the animal feel this and respond accordingly. Shanti has a very professional demeanor, great hands on talent and unique skills, and I recommend herwithout reservation. Anne Feingold from Urban Cat Project
