So, I do not use any plastic perches or wood dowels in my birdie cages, but Winnie's cage opens at the top to create a place to perch. The perch for the top and the rest of the perched for the cage are wood dowels. I never put the wood dowels in the cage (I bought new) but today when we opened the top for the first time we didn't know what else to use. So we put the wood dowel in. What is the negative on using the wood dowel? Any perches out there that might be long enough to extend across this opening?
