Shopping List:
Milk.
Eggs.
Cheese.
Petchup And Meowstard.
P.S. NOT Catsup.
Interestingly, according to cats (and Amazon reviews) Meowstard Nutritional Condiment Dry Cat Food does not compare to the dog version, Petchup Nutritional Condiment Dry Dog Food. But in case your wondering, it may not be the cats actually reviewing it. As Dana (presumably human) says:
It smells like fish vomit mixed with used baby diapers that has all been left out in the sun for a week.
Hmm, maybe best to play it safe and put that catsup back on the shopping list after all.
