The dog was eating the cats' food, so I put it up on the table. The cat is apparently too stupid to find it, so she turned to the dog's food.
They're all gonna die.
When my cats run out of food and I didn't have the forethought to go get them more before they run out, I fill their bowl full of dog food until I get them cat food. (It happens at least 2 times every 6 months. It's usually for one day.)
