A Note for Concerned Owners

While you might see Rats kept in a C&C Cage (Cuboid and Coroplast), it isn't quite the ideal setup for their unique needs. The biggest challenge here is not having quite enough floor space or enough room for fun activities. Over time, this can make your pet feel a bit stressed or lead to health concerns that are easily avoided with a more optimized home.

Creating a Cozy, Safe Climate

Just like us, Rats need to feel 'just right' in their environment. Inside the C&C Cage (Cuboid and Coroplast), it's important to set up a 'Warm Zone' and a 'Cool Spot.' The cozy side should stay around 68°F–78°F (20°C–25°C). This balance allows them to move around and find the temperature that makes them most comfortable, keeping them active and happy.

Bringing Their World to Life

For Rats, their enclosure is where they spend most of their time. To keep their curious minds busy, we recommend adding some fun, natural activities. This includes soft hammocks, climbing nets, and puzzles that hide their favorite treats. These simple additions help them use their natural instincts and prevent the 'boredom' that can sometimes happen in a plain or small space.
