Ok, so I moved my too males to tubs temporarliy until my rack system comes this week. One of them has still been eating and the other hasnt had a decent meal for a month. He was eating small rats. Both temps and humidity are fine. The one not feeding is 6 months old. his last rat was on the 20th of last month and he had a fat little mouse about two weeks ago...
could it be stress? he does seem to wander a little.
