I modeled a cage based on my chinchilla's. It includes a water bottle, a food bowl, and a small platform with a ladder. The food bowl has small hooks that appear latched onto the cage bar. The bars in line with the door have a small cut so it appears more realistic. The entire cage with everything included is approximately 60,000 vertices, give or take, but I plan on attempting to lower this number a bit. I am new to Blender and 3D art in general, but I am hoping to improve by sharing what I make.
