DIY: Guinea pig cage that was a TV unit in a former life. A ramp connects the 2 levels and there is a sheltered sleeping area plus lots of storage. The guinea pigs' favourite spot to sit is right in the middle of the ramp.
Drill or cut a 'feeding' hole near the bottom, small enough that your bird's head can't get stuck in it. Next poke or drill a hanging hole in the lid. Lastly fill it with hay or paper shred plus seeds and treats throughout!
