When cats engage in destructive behavior there is a reason. You are the one that has to figure out that reason. Will it be easy, most likely not. Sorry, but true

Most common reasons: Medical and either stress or their dislike of something/someone.

You said she had a recent check up and was fine, my suggestion is to call your vet and tell them what is happening, maybe they will suggest something.

What or whom is making Ginger upset? Ok, I realize that is easier said then answered, but think about it, and if you must, keep a log of when the distructive behavior happens. Does it happen after a petting session? After another kitty gets attention? She can't get from one place to another easily?

What is happening in your house? Have there been strange people in and out lately? Have you painted, remodeled or moved furniture? Bought something new? Got rid of something old (that she liked?)

You need to play dective and figure out what may be bothering her to promote this type of problem. Sure it would be much easier if we could just ask but then they wouldn'd be cats then

My first concern, because of her age would be to talk to her vet. At her age things can change in her body fast. With all seniors, we need to be patient and try to help them through these tough times. I realize that Ginger may not be your favorite, but maybe, just maybe she knows her time is coming, and she is trying to tell you someting. Because we can't listen, LOOK!!

Good luck and please keep us up to date on her!
