I've a cat I took responsibility for a year ago. He is now 2 years old. He was 'fixed' before I got him. He was never declawed. He is usually REALLY good about not scratching furniture or things he shouldn't. Until Saturday morning. I left my closet open a crack, and he is a curious fellow, and loves the closet for some reason.
Ovarian dysgenesis is a major cause of premature menopause. Ovarian dysgenesis is seen in 30% of the cases.[3] Sex chromosome anomalies predominate as a cause. The commonest abnormality is 45X0 (Turner's syndrome). Chromosomal abnormalities are reported in 10-20% of cases involving X sex chromosomes.[3]
Most Common Cause. A lack of estrogen is the most common cause of postmenopausal spotting in women not taking hormone therapy. Estrogen production drops to a low level after menopause, causing the tissues of both the vagina and uterus can become dry, thin and fragile. This is known as atrophy, which can cause bleeding.
