I have had a jungle carpet for some time now. But he has gone for so long only eating mice. He has gotten large enough to eat small rats for some time now, But when I first started feeding rats, He would smell them and then ignore them because, I am guessing, They didn't smell like the normal mice that he had been getting. He would always go right up to any food item and flick it with his tongue and if it didn't smell just like the last meal, he would ignore it. Well Finally, He is taking small rats while in the past he would take 1 maybe 2 mice. This is the first time that he has a large bulge in his body, Not that the size of the bulge matters! I am hopefull that "Shag" will start to go through another growth spurt! He's only about 2 to 3 years old, though I will have to go back through my records to be sure.
