Our Cats tail got stuck in the door and caused the door hinge to move enough to crack the nylon cam and we were wondering why the cat sat next to the refrigerator all after noon one day and let my 4 year old pet him (maul) when that never happens

Removed cats tail and proceeded to look for parts on line. received parts. stacked a set of books under raised door after unloading items from door to reduce wieght unbolted both sides of hinge. Reassembled both hinges. pulled books out and done in 15 minutes. Works better than new!! The cat no longer goes near the open doors. Fixed 2 problems!!
