I feed my cats Waltham's Duck and Rice. I have to get it from the vet so it's not as easy to pick up a bag when I run out. My boyfriend picked up an interim bag of Whiskas. Now that they are back to the ol' Walthams they are on strike eating only what they need to survive, meowing and begging for me to give them the "good" stuff. I've bought small boxes/bags of other cat foods to hold them over before but it was never a problem untill they got a taste of this. Whiskas is the McDonalds of catfoods! You can see the grease on it. Well, obviously they aren't going to starve because they are pecking their food. But I have to come to the conclusion that Whiskas is laced with kitty crack.
