Thompson, I love the idea of a borderline collie. And I love the story about her finding the keys.

What I learned about cat food may apply to farty dogs. Supermarket pet food contains plant fiber to bulk it up. This is not natural food for cats, and it irritates the digestive tract, producing a state of near-diarrhea. The result is a stinky litter box.

Buying better food, such as Iams or Science Diet, makes for a healthier cat and a nicer box. The food costs more per bag, but the cat needs less of it.

Worth trying with dogs, I think.
