And he's housebroken

Flea farming apparently isn't as simple as it sounds, soparasitologists at Cornell University in Ithaca, N.Y., have developed an artificial dog to raise fleas in a closed environment where they can keep an eye on the pesky critters. A mongrel arrangement of tubing, sieves and glass jars, the "dog' carries its fleas near a plastic skin-like membrane, flooded on the other side by warmed blood circulating through the tubes. After feeding on the blood through the membrane, the contented fleas produce eggs, which fall through sieves and are collected. With several generations of fleas at hand, the scientists thus far have concluded that fleas actually prefer walking to hopping.
