what about inventing an electronical way to catch rodents?

That's great! In order to make a small invention, here are some steps you can follow:

1. Identify a problem or need: Think about an everyday problem or something that you feel could be improved. This will be the basis for your invention.

2. Research existing solutions: Look for any existing inventions or products that already address the problem you've identified. This will help you understand what's already out there and how your invention can be unique and different.

3. Brainstorm ideas: Take some time to generate as many ideas as possible. Write down all your thoughts and consider different approaches or perspectives. Don't worry about evaluating them at this stage – just let your creativity flow.

4. Select the best idea: After brainstorming, review your ideas and choose the one that seems the most promising and feasible. Consider factors such as cost, resources, and practicality in selecting your idea.

5. Create a prototype: A prototype is a basic version of your invention that allows you to test its functionality and gather feedback. Start by sketching your invention and then consider creating a physical model or a digital representation using tools such as 3D printing or CAD software.

6. Test and refine: Once you have a prototype, test it out to see how well it works. Identify any flaws or areas for improvement and make the necessary adjustments. Repeat this testing and refining process until you are satisfied with the functionality and usability of your invention.

7. Protect your invention: If your invention has market potential, you may want to consider intellectual property protection, such as filing for a patent or trademark. Consulting with a patent attorney or intellectual property specialist can help guide you through this process.

8. Market and launch: Finally, if you're interested in commercializing your invention, you'll need to develop a marketing strategy and determine the best way to bring it to market. This could involve manufacturing, distribution, and sales. Consider seeking advice from industry experts or entrepreneurs who have experience in bringing inventions to market.

Remember, making an invention is a creative process, and it may take time and iteration to bring your idea to fruition. Stay persistent, seek feedback, and enjoy the journey of innovation!
