My guys eat whole leafy greens clipped to the side of their cage. All other veggies I chop in a food processor and serve in a dish. I have tried giving them a raw broccoli spear clipped to the side of their cage like the greens but they would not eat it. Tonight I lightly cooked a couple of spears in the microwave and they are munching away! I did let it cool completely before giving it to them. It is fun to see them enjoying something different!
