Bird Bath for Parrots

My birds freak out when I move their bath in and out of their cage. Also they splash water out of the cage on my carpet. So I designed this bath so that I only need to tip the main basin over to get out the gross water and make it so I can attach it to the roof of the cage with zip ties so any water they splash out will land in their litter. The basin can be removed for a good scrub every now and then but this way my birds wont lose their minds every time I need to clean their water. I recommend printing with tree supports
