Does my cat possibly hold stud tail?
she is a 3 year old spayed female,
and for the past while i notice she had greasy hair especially on her tail so i took a look at it a while ago and the skin looked bluish next to little blackish specks all over in one spot...
Soap and water minister to clean off a lot of the grease, but it's not a full cure.
If *really* bleak, you might be forced to shave the tail in the section where the "stud tail" is until you attain it cleared up.
Clean w/ a soft tooth brush & mild shampoo. Sebolux (sp?) from the vet is the best shampoo, it is sulfur based like full-grown acne medication.
Once you get it really clean, use a daily vinegar rinse to cut the grease from the skin w/out damaging the coat. If you can find one of those bottles w/ a sponge on it for moistening stamps - even better... use it to "paint" the vinegar on.
