House Wrens nest inside tree holes and nest boxes. As the season progresses their nests can become infested with mites and other parasites that feed on the wren nestlings. Perhaps to fight this problem, wrens often add spider egg sacs into the materials they build their nests from. In lab studies, once the spiders hatched, they helped the wrens by devouring the nest parasites.

Sam seemed quite upset over the blow to feline superiority.
