Hello:

 

That's quite a strange question. Can't say that we see that very often in cats.

 

My first thought is that this situation is related in some way to the diabetes. Whether this is a primary effect of the disease on the production of the keratin in the nails or some infection (bacterial or fungal) secondary to the diabetes is not clear.

 

I think it would be wise to do some cytology of the nail beds. If this is bacterial or fungal, a cytology may be able to identify the organisms. A cytology is done by taking some of the material from the source (in this case the nails and nail beds) and smearing it onto a glass slide and evaluating it under a microscope. It's possible that a culture may need to be done if cytology is not definitive. These tests would be able to clarify if medications are indicated and which ones. Antibiotics would be used if the problem was bacterial. Antifungals would be used if it was fungal.

 

If neither is identified, it may be related to the hormonal and metabolic effects of the diabetes itself. Then it would be vital to get the diabetes very well controlled in order for the secondary issues to resolve.

 

Hope these thoughts help.

  • My oldest male cat had a seizure this evening. This site was the first place I could think of to go after the seizure had passed. Dr. Lucy was fantastic and she was spot on! Debbie USA
  • I must tell you I found this site by accident and was amazed when I asked a question of the Veteranians online. I wish I could have found it sooner it could have made such a difference in the outcome of my pet's surgery. However, I am passing along the information to my sister-in-law (a cat-rescue person who is also a nurse), and perhaps it will help someone else who may experience the same problem. The doctor who answered my question was amazing, and while it didn't come it time to change the outcome of my situation, it is reassuring to know the caliber of Vets/Doctors that you have at JustAnswer. Thank you for being there. Alice H. Jacksonville, Fl.
  • Wonderful service, prompt, efficient, and accurate. Couldn't have asked for more. I cannot thank you enough for your help. Mary C. Freshfield, Liverpool, UK
