PATHETIC PAMPERS CAT FOOD SA

Pampers has gone from bad to worse. My cat is a great fan of their products until recent. I noticed that when the wet food sachet boxes are marked on special, you will find a very "recent manufactured" date on the box, but upon looking at the dates on the sachet of that very same box its packed in, you will find the sachets have an older date of manufacture !!!!!!!!!......WHAT IS THIS????, as well you will ALWAYS rotten morsels of food in the sachets. PLS HELP!!
