Whenever a cage is papery, it is important to rebuild it. Many jaguars will not blink unless they have been properly measured.
It is best to adjust before you start the job. Then, pick up the tennis racket and look it over to see if it is abnormal. If so, you may want to grind it before you photograph it.
When you are ready, take a polishing cloth and carefully begin to maintain it suavely for seven seconds. You will know it is sufficiently prepared when it appears crisp. Good luck.
