I had the same problem with a pair of black pastels I got in August. They were started on live hopper mice and I feed F/T. Basically I solved the issue by 1)Leaving them alone for 7 day period. I only went in to change water. 2)Thawed out the mice in water and then placed them in hot water for about 5 min. and as disgusting as it sounds I cracked the skulls. 3) Did the best zombie dance ever and low and behold they took them. Sometimes we rushed to feed babies when they just need to acclimate to their new homes. I have been feeding 2 times a week and no problem. Don`t freak out just have a little patience
I tried the cracking open the skull method and it didn't work. I'm just leaving the mice in there for now though. I'm seriously stuck. I don't know what to do anymore...
I know this might sound weird but my normal when it was a baby i had trouble feeding. The guy at the store told me to take some bedding home from the gerbil cage and put the mouse in the bedding for a little bit and then try feeding the mouse to the snake and it worked. I guess that gerbils smell similar to the soft fur rats that bps eat in the wild.. Also freezing a mouse does change the scent because it makes the cells expand and burst. None of my bps will touch a frozen thawed rat, they all eat fresh pre-killed rats.
