>>ok well what i have looke like a pile of mush, looks kinda slimy but definately not resembling a mouse thats for sure...
Assuming the mouse is eaten normally, the tail is one of the LAST things to get digested. If you see something that looks like a tail and maybe two hind legs, it is likely a regurg. regurg doesn't contain the black undigested matter and white, pasty/chalky urates, either. Snakes can regurg from immediately after swallowing a meal until ANY time that it leaves the stomach. Depe4nding on the temps, that can be OVER a week. If your temps are OK, you usually shouldn't have a regurg in over 5 days or so.
With that said, the timing of the regurg depends on WHY the snake regurged. If it is stress, it can be ANYTIME there is even a SMALL bump. Cool temp spike? Even a day or two after the bump disappears. Disease? it depends on the disease! Et alias.
