my guys(macaws) do not do the cage bottom, even when i put forage toys down. sometimes i see them shredded but i think that they go down, grab it, then back up. I think they are more arboreal vs some of the cockys who are semi scroungers. my cockys will go down to the cage bottom and pick the paper thru the bars, search for missed treats, etc. bounce around like pogo sticks...
