Lower quality product and terrible packaging
The new recipe is far from the quality it used to be. Now, the quibbles are covered in dust. Also, the packaging used to have a zipper for resealing. No more, once the 6.5 kg package is open, it's up to you to figure out how to keep it sealed (I don't know of any cat owner who goes through a 6.5 kg bag in a week or two).
Leaving three stars because my cat still eats them, and it's the only brand I know of that makes large quibbles.
