Supracaudal Gland Hyperplasia in Cats
Stud tail is commonly seen in intact male cats but can also be seen in neutered males and females. It results in skin disease at the base of the tail.
Symptoms and Types
- Greasy (sometimes matted) hair at the base of the tail
- Missing hair at the base of the tail
- Blackheads (comedones) on the skin at the base of the tail
- Waxy substance on the skin and hair at the base of the tail
- Skin infection at the base of the tail
- A foul odor
The supracaudal gland at the base of the tail contains sebaceous glands that secrete an oily substance known as sebum. In stud tail, these glands secrete abnormal amounts of sebum. The condition is also known as supracaudal gland hyperplasia.
Stud tail is most often seen in intact male cats because male hormones encourage increased secretion of sebum. However, it is possible for female cats and neutered male cats to also suffer from the condition.
Diagnosis is based on physical examination and the presence of typical symptoms at the base of the tail.
