We just got a sweet green cheeked conure from Petsmart, and also have a dog. Unless if the two of us are at home, we have to leave the cage above our bookshelf, which is way above eye level. The lady from Petsmart said that we should not put the cage above eye level. Is this true? I hear from some it's a myth, and some that it's true. This is for the safety for the conure. What do you think?
