Hi there,

Just a few questions to clarify the situation:

1. How long has this been going on?
2. Is he urinating normally, or straining, urinating frequently, in different locations?
3. Are there any bumps or scabs, etc, where the hair is missing?
4. Is he on any medication now?
5. Do you give/apply monthly flea preventive?
Customer: replied 4 years ago.
1: Several months.
2: No
3: Sores, when he keeps on licking after the hair is gone.
4: Other than the Megesterol Acetate - no.
5: No.
He has three brothers, all inside cats that never go out.
Expert:  Dr. Gene replied 4 years ago.
Has he already been given the megestrol?
Customer: replied 4 years ago.
Yes.

20 mg pill ....
1/4 pill on Thursday, Friday and Saturday.
1/4 pill on each Saturday after that.

Well... Megestrol acetate is a treatment that used to be used commonly to treat hormonal related hair loss and some other skin conditions in cats. Over time, this medication has fallen out of favor because of its potentially serious side effects (eg diabetes), because other, safer alternatives were found and because our understanding of skin diseases in cats has improved...

I suspect that your kitty has some form of allergies: food, airborne or flea bite hypersensitivity. Scabs on the skin may indicate a bacterial infection, which needs to be treated with a long course of antibiotic...

My recommendation is to stop megestrol and start a combination of the following:

1. At least a 30 day course of antibiotic (or two injections of long acting antibiotic Convenia, 2 weeks apart)
2. Strict flea control (even indoor cats get fleas!!) using monthly preventive such as Revolution, Advantage Multi or Frontline Plus
3. Hypoallergenic diet (see link below) for at least 3 months
4. Fish oil supplement (any product for cats)
5. Antihistamine such as diphenhydramine (Benadryl), hydroxyzine or chlorpheniramine.

If no improvement 1 month after starting all of these things together, I would recommend seeing a veterinary dermatologist...

Hope this helps; please let me know if you have any other questions; best of luck!
