Leapin Lizards!

So we're having a food chain experiment in the house. We've been infested with ants, roaches and lizards. Shouldn't it follow that Shalosh eats the lizards who eat the roaches who eat the ants? Apparently this logic is not panning out. I spent 30 mintes the other day with a cardboard flap "guiding" the lizard to the door. Shalosh steps on the roaches but doesn't completely kill them so it's just toture. Shalosh also plays with the lizards and takes them to our bedroom. Won't that be pleasant when one of us wakes up with a lizard on our face. Finally the ants. Nobody takes care of the ants except the exterminator and he wasn't so successful. Maybe the problem is that the roaches are in the living room; the ants are in the bathroom; and the lizards are in the kitchen. We need to get everyone together and see what happens.
