for the past year or so, i've been feeding my snake those frozen mice found at petsmart. i've been giving him two large mice every other week for a while now, and he was fine with it. recently though, he's been only eating one every other week and ignoring the other one. i gave him one mouse today and when i checked back a couple hours later, it was still on the ground, but it looked like it had blood around the front of the mouse. what exactly could be causing this? should i go to petsmart and pick up some smaller mice and try and get him to eat those first?
