My male that is 4yrs old now stopped eating for 8 months in 07. I was worried but he never lost weight and shed regularly also. I tried everything to get him back on feed but with no luck so I finally didnt try for about three weeks and then tried a mouse. He ate it and then ate 3 more that night and I fed him mice for a couple weeks and then went back to small rats. He hasnt stopped eating since and is now chowing on medium to large rats. Give him time as long as he isnt losing weight you should be just fine. Good luck.
