I really doubt these little furbabies are capable of spite. Maybe it's just a stage? Don't go by me, I learn as I go. Gizmo has been on i/d for quite a while as he has problems with HGE and Pancreatitis. I picked up some of the canned and dry Chicken Soup at the feed store (nobody else around here sells it) after reading up on it and have had no problems and he seems to like it a lot. He eats a little wet in the morning and evening, I leave dry out during the day..he eats both. Good luck.
