Taz was that way. If I even walked near where his food dish was he was meowing his head off at me. And I learned the trick early on too. I would put just a few pieces in his dish, OR I would pour the food from the dish into another dish and then back into the original dish, mixed with some fresh.

Now, for Paizly and Jax they do not meow at me to fill the dish. Jax always has a dish of food in his room. But he prefers to eat Paizly's food. So I do have to check it all the time to make sure there is food in it. He is a PIGGIE!!
