Hello I am Dr. Joey. Thanks for trusting me to help you and your pet today. I am a licensed veterinarian with over 15 years of experience. I look forward to working with you.
This does sound concerning. The most common causes of hair loss in a kitten this young is either trauma from over grooming mother or other kitten suckling, ringworm
, other source of infection, nutritional issue (unlikey since other are doing great) or endoparasitic problem (mites, fleas).
I am most concerned about ringworm. It may be worth having your veterinarian start a ringworm culture, which takes 2 weeks to get results. But the other possibility is that this cat has some kind of congenital hair abnormality.
Given the kitten's age, you can take a wait and see approach for now, as long as there are no other cats in the household developing hairless, and the no person in the household has no lesions (which would indicate ringworm). At this age most angifungal medications cannot be used by mouth, which is the most effective route. We might have to try topical but because, again, it is so young I really would rather have a diagnosis than risk introducing any sort of potentially ingested medication at this age when liver/kidneys
are still developing.
I am at a point I need to know what questions you have. We can continue our dialogue in this setting.
I hope that the information I provided has been helpful.
