I saw a feeder toy on here and thought about making one. I have made two now. The second one took about 20 mins. One piece of wood, one piece of plywood cut into two squares, a spade cutting drill bit and a lot of sanding.
I came up with this
It was the second easiest thing I have ever made for a pet. The easiest being a perch for a budgie from a length of dowel. lol
