I've been trying to switch my BP to F/T mice for about 3.5 weeks, and he has yet to go for it. During this time, he has also become VERY active in his tub. Roaming a lot, often during the day, and frequently trying to push the lid up with his head (presumably to get out). He also now comes out of his hides any chance I go near his tub to see what's going on. Before trying to make the switch to F/T, he used to eat every 5 days like clockwork and tended to be more active a day before feeding. Otherwise, he kept to his hides, more in line with the classic "A hiding BP is a happy BP."

I'm not sure if his change in behavior is due to his hunger or if he's stressed. Anything to worry about or look for at this point? Also, he's about 6 months old and ~470g at last weigh in. I know adults can go months (or a year even) without eating, but how long is too long for a BP this age?

Husbandry is good, as far as I can tell. 2 hides, water bowl, paper towels, hot side belly temp 90-93, cool side ambient 78-81. I attempt feeding a F/T mouse every 5 days at night in low-light conditions.
