Over 12 years have passed since I first decided to share my best pal Astro’s story with the world. In 2006, when he was diagnosed with advanced kidney disease, I was told that there was little that could be done to prolong his life beyond a few extra months, or optimistically, a year or so with questionable quality of life. Unfortunately, to this day, this is still the standard prognosis many people will receive for their newly diagnosed chronic kidney failure pet.

The reasons are simple, the average treatment protocol still involves mostly the same handful of drugs that produce very mediocre results, commercial renal diets that provide reduced protein content which some studies have put into question as an optimal long term strategy, and fluid therapy in the form of IV’s or Sub-Q’s which can, if not administered correctly, add an unnecessary work-load to the kidneys.

I did not accept these limited treatment options and the dire prognosis offered Astro, and so, relying on my medical training and based on research I had conducted on systemic inflammation, I set about formulating a solution targeted at the root mechanisms of chronic kidney pathology.

Astro’s condition stabilized and his health began to improve with the administration of the formulation that was created for, and named after, him. It continued to improve, week by week and month to month. His recovery was dramatic, one might even say miraculous.

All these years later, the journey that Astro and I embarked on together has grown to encompass many thousands of people around the globe and their chronic kidney disease pets. His story touched and inspired many people who felt helpless as they watched their best friend suffer and waste away daily, to fight and win time and quality of life for their furry buddies rather than surrendering them to a “kind assisted passing”.

Building upon and investing in research focused on the concept of targeting the disease at its root, 2 new products have since been developed to work synergistically with Astro’s Oil™ Advanced Renal Care Formula to more effectively address kidney pathology. The feedback, as you can read in the testimonials page, has been overwhelmingly positive and the results impressive.

We invite you to join the thousands of people worldwide with kidney disease pets who have achieved superb results and trust us to help you achieve the best possible results for your pet as well.

“Can our Natural Formulations
play a Central role in the management of your
pet’s Kidney Disease ?”

Yes! Read below to find out how

Astro’s Oil™ Kidney Care Products, the Advanced Renal Care Formula, Nitrogen-Creatinine Scrub and Renal Care Proteinwere designed to work synergistically 

The Advanced Renal Care Formula actively addresses kidney pathology by interfering with the inflammatory mechanism that propagates the disease

The Nitrogen-Creatinine Scrub detoxifies by using the digestive tract to help clear excess metabolic toxins, nitrogen,  creatinine, and phosphorus from the system

The Renal Care Protein fortifies pets in a number of ways; by helping them gain and maintain lean muscle mass, by helping to sustain recommended levels of essential amino acids in the serum to staves off metabolic acidosis, and by providing very low molecular weight peptides and free form amino acid building blocks to generate vital protein metabolism and cellular regeneration

Astro’s Oil™ Advanced Renal Care Formula

Astro’s Oil™ Advanced Renal Care Formula is the 3rd generation of the formulation introduced in 2007. It is designed to address inflammation of kidney parenchymal tissue which can help restore function to the affected tissue before it progresses to cicatrization (scarring) with permanent loss of kidney function.

Astro’s Oil™ Nitrogen-Creatinine Scrub

Astro’s Oil™ Nitrogen-Creatinine Scrub is a supplement that enhances the pet’s gut microbiome flora. As the bacteria proliferate they take up nitrogen and creatinine and are then excreted in the stool. It also reduces serum phosphorous level.

Astro’s Oil™ Renal Care Protein

Astro’s Oil™ Renal Care Protein is a supplement designed to help pets with kidney disease gain and maintain lean muscle mass. It also helps stave off metabolic acidosis.


“I would like to publicly thank Edmond for marketing Astro’s Oil when he did. I have been a customer I guess from almost the beginning! My two Siamese cat littermate-sisters were sent home to die in 2007 (“just give them Pepsid to soothe their stomachs”, said their vet). I refused to accept that prognosis and started scouring the internet for SOMETHING alternative to try, and found Astro’s Oil. That was when the cats were both 12 – and now the one we still have is 21! And the other one lived to be 19-1/2, and we did NOT lose her from CRF. Thanks, Edmond, for giving us so many, many more quality years with Ginny and Neffy. May there be many more to come for Ginny and all of the other pets who will be given another chance due to Astro’s Oil!”

“I can’t thank Edmond enough… Several times Edmond came to my rescue when I was stressed out of my mind. The vets couldn’t believe I had managed to keep my companions (3 of whom got renal failure syndrome one after the other) alive as long as I did. Without Edmond, the extra life time I had with my companions would have been impossible. I cannot recommend this man’s work and expertise enough. Every pet owner should know about him. I wish Edmond was training vets, their work and service would greatly improve. I have never met Edmond face to face, but after the gut-wrenching, I went through with my little critters, I’ve got to say I love this guy! He’s one in a million!

“I am so very pleased with my dog Honey’s response to Astro’s Oil!!! A miraculous burst of energy and appetite!! I must write an article to let everyone know of this wonderful product that you have invented, for your beloved Astro!
My husband was very skeptical, but he has just reminded me today that I need to order MORE of Astro’s oil!!

“This is “Blue” our 5 year old ragdoll, asking for more food. (3 months ago, we had to syringe feed him!) Enjoy the reward of your research which now helps us all. My vet was blown away by the blood test results.

“I wanted to give you the greatest news and latest update… we started Mary on Astro’s Oil at the end of April… while delivering 100cc of IV fluids. Mary was functioning on 25% of one kidney only…with the (vet) recommendation to put her down because she would only last 10 days to two weeks.  I am so grateful to say that this weeks lab results came back and my Vets were astonished.  Not only did she gain a pound and a half in three months but her blood results were almost normal. I also had weaned her off fluids and waited three weeks on purpose before taking her for blood work… My vets were so impressed that they told me they would research your products and contact you… Amesbury Animal Hospital..Dr. Candee and Dr. Smith…their reaction to Mary was true amazement, more like disbelief… they actually thought Mary was beyond help.”
