When I first saw Herman he was out of condition and his beak was overgrown.
So first thing was a trip to the vets to cut that beak back so he could have a chance to grow it properly this time.
Cockatoos need lots of things to chew to keep their beaks in good order and hence themselves in good health.
Not many people know cockatoos are carnivorous.
Herman likes the shower room
Herman likes having showers
Herman also likes to destroy flowers

And after the walk, what better than another shower.
