We have had Kaysa for about 10 years now, Ryan got her as a kitten while we were dating.
She has started marking the house, for the first time in her life. We had her tested and there isn't anything physically wrong with her, just maybe mentally so we are going to try out some medication for anxiety called Amitriptyline.
Keep her in your prayers since the only other alternative is putting her to sleep.
Update: Kaysa was given away to a family of six during our garage sale. She is seaming to be doing well there. We do miss her still but really are glad she is not dead.
