After considering rehoming my pet bird, I met someone who wanted it, and I agreed to let her have the bird for a week or two to see how the bird would do. After I dropped the bird off, I really felt concerned about the home since it was a really old trailer. I told the woman that I just couldn't part with the bird, and asked if I could go ahead and pick the bird up the next day. The woman said I could. The next day, when I went to get the bird, the lady said no, and that I couldn't even come visit to check on the bird. I can provide a vet bill and my adoption papers from when I adopted the bird. How do I go about getting the bird back?
