This is my first post and I know a very common question.So,please be patient with me.I got "Charles" as a Christmas gift from my wife and son at Christmas of 2012.He,or she,was probably under 6 months old.He is now probably over 2 feet and looks healthy.He ate very well and weekly until December of 2013.He refused all food until early to mid April of this year and ate two small rats a week apart.I thought he would go back to regular feeding but has refused all food since then.I try a small rat about every week to ten days.The last time he ate,I put him in a separate container and he ate the two small rats in that.I have since tried to feed him in the container and in his regular cage.He is housed in a 20 gal aquarium.I have foil over one end and a heat mat and 60m watt black light bulb on the other end.Temps are good.Humidity is low but I mist the cage frequently.Is he probably just being picky or just not hungry?He seems healthy other than not eating.He comes out some at night but not all the time.I have two hide boxes and he usually stays in one of them 95% of the time.Should I just continue to try and feed him every few weeks?I just hate wasting these rats.I tried a large mouse last time but he refused that too.
