I have a few dozen tricks. I will start with a couple more obvious ones that are worth trying first. A new food item will sometimes really spark something. I would try an African Soft Fur or go to a pet shop and buy a Gerbil. In my experience, a Gerbil really gives off a scent that perks up a BP. Try a Gerbil first and if that doesn't work, try an African Soft Fur. Good Luck and please keep us posted.
