One thing I do have to add,the cockatiel-style bars will not work
well with a Sennie,I can tell you from experience that in the
long run,they'll be out of there,they bend the bars until they
pop off,and they have pretty strong little beaks.Same with the
materials in your cage,they are pretty voracious chewers,I had to
have Manzanita in all my Sennies cages,otherwise they'd end up
with nowhere to sit!
