Because it’s absolutely impossible to open sachets of the disgusting, smelly, liquid filled, gravy ones that the furry overlords demand without ripping them part way, splashing it up the wall, getting it on your top, in your eye and on the floor rather than the bowl you’ve got on the counter?
And you can't recycle the bastards without washing them out and taking them to one supermarket in a town your mother in law lives in 6 miles away?
And no cat in the history of cat domination of the human species has ever eaten the beef flavour.
Won’t someone think of the Cat Slaves?
