Also, if your snake is growing and shedding, it is getting enough food. A lot of people try to benchmark thier snakes. They say it should be so big after so many months. You should not do this. Three snakes fed the exact same diet will grow at three different rates. I weigh my actively growing snakes every few weeks and as long as weight is increasing and I am seeing regular sheds, all is good. I usually feed less than 10 percent. Once the snake has reached near maximum size, I don't even feed that much. Unless you have an extremely active Colubrid, it just is not needed.
