I have 1 pair WC AD BP that I purchased last Nov .

Everything I offered to them is very good even the vivarium set .

I keeping them in my rack system tubs including heating , hiding , water , substrate ... etc . They have everything they want ( I guess) .

Howevery , the problem is :

They are still no feeidng and refuse any rodents I tried .

I tried mice , rats , hamsters , rabbits . ( I don't wanna trying birds).

I really do not wnat to force feed these BP since they are very east to get stress from keepers .

I am not guessing maybe the problem is their substrate . It's nwepaper . I don't know if they will feel more stress to stay on newpaper (All my snakes are doing fine on newspaper). I am considering maybe I sould change their substrate from newpaper to aspen bedding . What do you think about this ? Or substrate is not the point ?

I really want to know if you exprienced keepers have any good method to solve this problem since most WC AD BP will refuse food for a long time .

thanks .
