If you can get them..... mix some pistachio shells in with dry food.
Thanks I can buy some pistachios, and give her the shells, but they have a lot of salt on them usually, don't they? Do I need to wash them, or is the salt ok for her? Can she have the pistachio nuts as well for treats?
I'm not sure how I could easily spread her food about. I had her hanging "treat thing" up towards the middle of her cage (it opens at one end) but I've moved it up near the door because it was too difficult to put her grass in it. I probably need to rethink her cage organisation - I've set up her food and feeding perch right in front of the door, which makes access to the rest of her cage for me a pain because I have to go under her perch - but it's the easiest for access to her bowls... Maybe I'll put it up higher. Maybe make a longer one and put it diagonally instead of across.... hmmm. So many ideas, so little knowledge
