Make sure the mouse is up to the correct temp around 100degrees, especially around the head. Also, try cutting into the head out the mouse to expose some brain smell and taste. My BP is extremely picky about the temp of the F/T.. too cold she looks the other way, just right.. bam! Hope it works for you
If it has already eaten 3 frozen thawed I would not offer live... If its hungry and your husbandry is spot on it will eat. Mine tends to eat 3-4 meals then skip 1 or 2 its just how BP's are.. they are picky and eat when they want not when you want them to....
Ball Can Be picky...
I remember My male Yb when i was buying him was established F/t Eater... and after 2-3 month he go on hunger strike...
He was interested but he dont strike.. after 6 week so F/T tug of war i offer him live and he is on live till now.. and eat like is no tomorrow...
Just make sure that you offer proper size of food and you and Him/her should be absolutely fine
