It won't take you long to learn his feeding schedule.
Something else that occurred to me after I shut down last night; Before I set up the 2nd tank to house the feeder mice, I would just toss all Fuzzy's mice into his tank when it came time to feed him and he'd catch them at his own pace. It was seeing how much the mice pooped in his tank while waiting to be caught that helped me realize the extra tank would be the way to go.
During that time, there was one mouse that didn't get eaten, and Fuzzy actually seemed to form a bond of some sorts with the **** thing. That mouse spent several days in the tank with Fuzzy and the snake just wouldn't eat it. He was fed other mice which he ate without a problem, but as soon as I would put the first mouse back in his tank, hoping he would eat it, he just refused. The 2 animals sort of "hung out" together! More than once I found the mouse asleep in Fuzzy's coils under his log.
The last thing I needed was a pet snake with a pet of its own, so I took the live mouse back to the place I bought him from and exchanged it for a different mouse, which Fuzzy immediately snapped up and ate.
Good luck with Donnie, and I'd love to see more pictures of him as he grows!
