I live near a reptile shop, and generally defer to their advice on things. Recently I had an interesting conversation with one of their employees. She said pacman frogs usually die of impaction because of a different, unrelated issue, such as weakness from poor breeding, injury or infection weakening them so they are unable to pass the accidentally ingested materials. She said, in addition, that the underlying cause usually goes undetected and impaction is given the full blame. Anyone else ever heard that?
