I was just shopping for cat food and came across a bag that was $5 cheaper than what we normally get, so naturally, I was excited that I could get the same stuff from a different brand for a better price. Of course, I had to make sure the bag wasn't just smaller or something, so I dragged it over to what we usually get. It was the same brand and I took another look at the bag I was holding. There was a dog on it. I was about to get my cats dog food. XD
