　　Non-tumorous ovarian cysts can be divided into two types:

　　The first is follicular cysts that secrete large amounts of estrogen, with symptoms including prolonged heat cycles or more frequent heat periods.

　　The second is luteal cysts that secrete progesterone, which can cause false pregnancy, lack of heat, or complications such as pyometra.

　　If you notice your cat’s heat cycle is abnormal, please take her to a veterinary hospital for diagnosis. (Source：PetsZone)
