Someone on one of the parrot forums I go on was trying to decide between an atom from MPBT and the Odd ball from Oliver's Garden.
I have both, although in different sizes, and figured I'd show comparative pictures on the forum to help her decide.
So here they are!
First, atom on the left, odd ball on the right.
I then figured it would be nice to use a bird as a model. So out Pixel came..
..and she would only stick to the atom. The odd ball was less stable (probably due to weight difference) on the couch so each time I would put her on the odd ball, this happened..
So out Joey came. He was quite happy on the odd ball!
