I am the owner of a Stimson's Python (bought Feb 2013). He was approx 3 years old then. I am having trouble getting him to eat, (last meal 2nd April 2013), he has not eaten in the last 14 months although regularly poos and drinks. He seems to have lengthened but is visually thinner and now does not grip as well when I hold him. Help, what do I do, how do I make him eat? He lies in a 4 foot terrarium with a 26 watt flourscent on in day times as well as a heat rock. He also has a 60 watt UV night light that comes on at dusk and runs for 10 hours.
