We recommend monitoring asymptomatic FeLV cats regularly by conducting a Complete Blood Count (CBC) including Reticulocyte count, and observing for early signs like gingivitis, stomatitis quarterly. If the results trend downwards, then you can begin treatment with RetroMAD1.

However, if you would like to start treating your cat while it is asymptomatic, then RetroMAD1 can be administered as follows:

1) By Oral Route
  • Dose: Ideally 0.30ml per kg, 30 – 45 minutes before a meal, food supplement or probiotics for optimal absorption.
  • Daily: 2 times a day with intervals not more than 12 hours apart.

2) Duration: It is not determinable how long it may take for a FeLV-positive cat to become FeLV-negative. The shortest time has been 3 months but we are aware some customers have treated their asymptomatic cats for a few years (with dosage reducing to 0.15mL per kg) while their cats continue to be FeLV-positive. The intent is to ensure that the cat remains asymptomatic throughout so as to lead a normal and active life. Alternatively, you may wish to consider keeping the 30ml Starter Pack on standby so that RetroMAD1 can be given quickly in the event symptoms develop one day.
