There are more than 200 million cats and 200 million dogs which are part of our family members today and growing. What is heartening to know is that the life expectancy of our pets has gone up significantly, some living to a ripe old age, allowing us to have a fuller life together. Better nutrition and more advanced veterinary care make this possible. With the COVID-19 pandemic, our pets have become our dearest companions as we turn towards them for comfort and joy during this difficult period.


Unfortunately, viral diseases afflicting cats and dogs are still present because antiviral therapeutics are not available until now. Feline Leukemia (FeLV), Feline Immunodeficiency Syndrome (FIV), Feline Infectious Peritonitis (FIP), Canine Parvovirosis (CPV2) and Canine Distemper (CDV) are some medically important viral diseases affecting cats and dogs worldwide. They are all fatal. The prevalence of these viral diseases varies from country to country, reaching up to 30% even in some developed countries. Pet owners are well acquainted with these viral diseases through community self-help groups and veterinarians.

“In over 100 cases of cats suffering from feline leukemia, presented by their owners from Germany, Malaysia, Singapore, South Africa, and the U.S. that received RetroMAD1TM treatment, the lives of all these cats improved so dramatically that owners could not believe what they witnessed. Without a doubt, RetroMAD1TM saves lives.”

RetroMAD1TM - The future of anti-viral treatment

With more than 10 years of research and development using a patented recombinant proteomic technology, RetroMAD1TM is the most advanced and true antiviral molecule that demonstrates excellent therapeutic value specifically targeting fatal viral diseases in cats and dogs namely FeLV, FIV, FIP, CPV2, and CDV. With its wide therapeutic index and ease of oral application, RetroMAD1TM is positioned as a drug of the first choice for veterinarians and pet owners in antiviral therapy and immune-modulator prophylaxis. RetroMAD1TM is further envisaged for use in individual pets and pets living in high-risk communities to aid in the prevention of the spread of these fatal diseases.


A broad-spectrum antiviral against medically important/fatal diseases of dogs and cats, RetroMAD1TM is

1.  An aqueous liquid for oral use, allowing patient and pet owner compliance;

2.  Safe up to 300mg per kg of body weight;

3.  Designed for community use* like in a shelter, breeding cattery or kennel.

* Similar to Pre-exposure prophylaxis (or PrEP) when people at very high risk from HIV infection take HIV medicine daily to lower their chances of getting infected
