Ok sweet well thats good to know about the lines, because they are not all over and she does seem to be a bit on the chubby side, before i got her she was being feed a medium rat weekly, and then i got her and she fasted for 4months and now is eating regulary, i am feeding her small rats , once every 2 weeks. I honestly do not know what the temp is inside the hides, what is the best way of measureing this!?
