My dad made new shelves for Moshi today! I bought KD pine at Home Depot, and they cut the boards for me. I threw away the awful plastic shelves his cage came with. Moshi was going insane! He spent 10 mins hoping from top to bottom, continually! Then he figured out he could chew them He seems SO much happier with his new boards! I got six boards altogether. It was $20 to make him new shelves
