Appetite doesn't seem to be a problem with my cats. In fact the black one just gets bigger and bigger. No matter how much he eats, he thinks he's starving. Mine are generally content with the store-bought stuff. But I do treat them with chicken and turkey when we humans have it.

Any time I make fish, the sit in front of the oven (or microwave) and cry while it bakes.

I have a recipe for fish in an herbed cream sauce that when I make it, I must lock the kitties away until we are done eating. But the last time I looked, I couldn't find the recipe :( I believe it had heavy cream, some lemon, and various herbs that taste good with fish.
