When I was a kid, our cats and dogs used to collaborate in heists together. Cats would leap acrobatically from counter to counter, trying to get you to drop the food. The dogs would slither between your feet to trip you.

i'm pretty lucky with just a pair of picky eaters who like one kind of kibble, one canned food and one flavor of greenies treats (heat-sealed bags only, the square containers aren't airtight i guess and get stale). one will eat bits of chicken if offered but she isn't overly enthusiastic about it.
