Is that a full Mainland retic? It's interesting, her growth seems very slow compared to my 50% dwarf retic, but I was using my snake to use up my uneaten rats when my collection was smaller, some weeks she would get multiple rats. At one year old she weighed about 25 pounds. Now I have plenty of other snakes to use them up and feed just one jumbo rat every 1-2 weeks, she is now just over 2 years old and weighs 37 pounds. The growth of your snake seems to be on par with my super dwarf / dwarf male retic which is much slower growing. How often do you feed and what size rodent?
