Lex is doing pretty much the same thing...but my spin on this particular problem is that I think he might be sneaking down to the basement (where I moved our cats food to) and eating April's food. I can't close the door because she roams the house and her litter box is down there so if she can't get to it she will have an accident somewhere else. I have to figure something out. I really don't want to change his food until it's time for adult food.
