Too big prey for a corn?

[Sylphie]

Hi all, I need your opinion about this "idea":

Month ago my Blizzard corn female (2 years old) was getting medicine for protozoa. She's now cured and can eat normally, but... she lost a lot of weight because of that illness.

After treatment she ate three times (22, 26 July, and 1 August), and everytime when I gave her the mice (f/t) she was playing with her for few hours. You know, poking lazily at her, slide the mouse around her tank, and finally lazily ate. She's nowmore than 2 weeks off food and today I thought that maybe due to her lost weight the adult mices are too big, and thats why she was "playing" with them and finally stopped eat.

Do you think that this may be the issue? She's around 192g (6.9oz), all the parametrs like temps and humidity are the same as always, I didn't mess with her cage decor, so that's really the only thing that may be wrong.

Normally I wouldn't be too worried about that going off food for that period of time, but she's already at the minimum side of the weight and I'm afraid of her losing too much.
