Manx with incontinence issues.?

My Manx hasn't had those problems thankfully. But she has had arthritis for a long time. Now that she is 15 it is getting quite a lot worse. I am giving her a couple of things for that and she hasn't had an attack for a while now. This probably doesn't help too much with your problem but I just had to tell you how much I love the Manx breed. Funny thing is, she is the first cat I had. After her I think all the others look funny with their long tails.
