Don't worry, she is just adjusting. Don't leave the mouse in with her over night. Give her another week alone before trying again. You can try different prey items. If she's not eating a mouse, try a rat pup. If she won't take it frozen, try live, ect. I wouldn't worry til it's been a couple of months or there is a sudden drop in weight. I got a clown in October and he just started eating last week. Turns out, he will only eat mice and I kept trying to get him to eat rats. Kinda feel dumb for not trying that sooner but hey, I'm still new to this
