- Secondary diabetes may be caused by use of steroid medications, the hormones of estrus, acromegaly, (spaying can resolve the diabetes), pregnancy, or other medical conditions such as Cushing's disease.
- Proligestone is used to control estrus in dogs and cats and has also been used to treat hypersexuality in dogs and cats.
- Alfaprostol is a luteolytic agent used injectably for scheduling of estrus in mares for purposes of planned breeding.
