Too many non-food particles. I have to add water & make it soupy for one of my cats. In doing so, little black flecks of varying sizes would appear in every serving. Upon close up inspection there was a consistent raised pattern in the flecks, indicating it was a manufactured product and not something naturally occurring in any of the ingredients. My personal opinion is that it is pieces from the rubber/plastic sheeting on the conveyor belts. Similar to thick shelf liner material. This was observed over several months, close to a year, of feeding to my cats. I switched to Sheba and do not find any particles of anything in that. Friskies is cheap for a reason. Quality control is not important.
