Not a bored parrot

Hi everyone,

Aka enjoys spending time in his cage when he's had enough of me or the floor of the flat, but his cage is next to a boring white wall. He speaks to it and the stuff in his cage, but I want to make the wall less boring.

I was thinking of using fabric paint on a sheet of fabric so I can draw colours and pictures and stuff so he doesn't stare at a blank wall when he is in there. He chooses to face the wall instead of the front of his cage, I don't know why, but I'd get so bored staring at a white wall for minutes at a time. Is fabric paint safe? I will definitely wait until its completely dry before I hang it from the wall to make sure the new fumes aren't there. If not fabric paint, then what paint can I use?

Thanks.
