I have a couple BP's that will only eat F/T mice and while it's not very cost effective to use mice to put on weight, I was wondering if I could supplement their feeding with a "high calorie" mouse.

What I mean by that is injecting the mouse with an organic food item that will boost the 40 gram mouse to that of a 100++ gram rat. I was curious if an intraperitoneal injection of a high fat and protein product into the abdomen of the mouse prior to feeding will increase the caloric intake of my picky, mice only pythons.

I'm wondering if that has ever been implemented and if there is a 'recipe' or concoction that has been tested and proven to supplement the feeding program with fussy eaters?

Thanks guys!
