I also pre-sent before feeding, he always comes looking for the food, I just switched over to F/T small rats with no problems, I hold the F/T rat with a pair of tongs up away from the substrate and it still takes him a several seconds before he strikes,we tried the seperate feeding tub but he would not eat, after feeding I leave him alone for a couple days without handling but still change his water and strighten up his cage, then we handle him every day until feeding time with no problems.
