Yesterday, i got a great idea. I thought that if i make origami paper ball my budgies would spend hours figuring out. So what i did was make 4 paper balls, each with increasing difficulty level, fill them with millet and placed them in their cage. As soon as my birdies heard the click, the rushed over the bowl. That is when the fun starts. All Chizu did was shred the paper, eat millet, and shred again. However, Pedro emptied the millet, dropped the ball and started playing football with it.Here is the pic of the paper balls:
Each took less than a minute and i am going to make some everyday. Hope you like it.
