What are the best ways to prevent hopper mice from escaping and potentially causing harm to snakes?

To prevent hopper mice from escaping and potentially causing harm to snakes, it is important to use secure enclosures with tight-fitting lids, regularly inspect and maintain the enclosures for any potential escape routes, and handle the mice carefully to minimize the risk of escape. Additionally, providing a suitable environment with appropriate hiding spots and enrichment for the mice can help reduce stress and prevent escape attempts.
