Ok , thanks I just checked again and the large lump is nearer to her tail. I am trying not to check on her anymore , and she is not being handled since eating of course. She usually eats on Friday and poops on Tuesday. Very small poop IMO. Even the largest mouse I could find was a bit thinner than her fattest part of her body. This rat was a smidge fatter than her fattest part.
I guess if nothing else I can expect a bigger more elaborate present out of her this week

How many days before I feed her again do you think? I had bumped out her feeding day this week from Friday to Saturday because I want to ultimately feed her on a Monday night or Tuesday. We are often out and about on the weekends , and when we are home on the weekends we are most likely going to handle her. So I ideally want her weekly feeding to be an early otherwise boring weeknight .
