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 condition often does not resolve although in some cases neutering your cat can solve the issue.

    Sweetie could have ‘stud tail’ which is an overproduction of oil from glands near the tail. It is common in male cats, hence the name, but can be seen in females as well. Allergies causing a skin infection would also be possible. I’d recommend seeing your veterinarian to have Sweetie examined.
