I tried mixing up my food in the blender which Fluffy liked much better, though he insisted that I add some baby food on top, after
I heat up the blended cat & baby food.
My Kitchen Aid blender is heavy and hard to clean, so after he finished that batch, I tried my food processor, which has a small bowl attachment to put inside the large bowl. It worked even better than the blender.
Unfortunately, Fluffy seems to be losing his appetite again.
