@west coast jungle: thanks you very much for the idea..i got the point of my snake being nervous.lot of my friend come and see the snake and some of them pick up the snake to choose before they bought them, i think is because of that two of them have this problem.
i must admit this all my fault and carelessness.
i hope after this i everything should be alright
thank you very much for all the help....i will let you guys know the result when they are start feeding
