There are several good ideas for building a DIY rat cage for rats. One option is to repurpose a large plastic storage bin by adding wire mesh panels for ventilation and attaching platforms and ramps for the rats to climb and explore. Another idea is to build a multi-level cage using wire shelving units, connecting them with zip ties and adding ramps and platforms. Additionally, using wooden crates or boxes to create a modular cage system can provide a customizable and spacious living environment for rats. It's important to ensure that the cage has plenty of space, ventilation, and opportunities for enrichment such as toys, hiding spots, and climbing structures. **
