Edible dog poo bags

The weak spot with most halfbaked dog poo collection systems is always getting the poo into the bag (except for those ideas that use robots - that's a different ball game entirely). Edible dog poo bags are designed to be placed inside your dog's food bowl where they will be eaten and pass through the digestive tract just like all the bits of wood, string, wrapping paper and toy cars that always seem to pass through undigested.

The inside of the bag is coated with tiny hairs all facing inward. This will trap matter inside using the wheat effect (Try holding an ear of wheat between your hands and rubbing them against each other, you'll see what I mean. There's probably an official word for this effect - ask google if you're really that interested).

At the beginning of the bag's journey all the food will be on the outside. As it travels through and the food gets digested it will slowly trap more and more matter on the inside, emerging from the other end with the poo neatly packaged within.

When you see the tie handle emerging just tug it out, tie it and bin it.

Infant version available from mid-2009, pending approval.
