Bummer. One of my '08 males is doing something odd. He constricts his rat pup.. and then just leaves it there. This has happened not one.. not even two.. but three times, and he has not had a meal in him yet. Last week I even left the rat in all night (shoebox tub) after making sure discreetly that it was dead. No go. Any advice? I am at my wit's end!
