Q. My cat has very thin brittle nails that split & break easily. He is otherwise healthy and has the same diet as his brother who has healthy thick nails
DR. MASSIMO ORIOLES, DVM, MRCVS
A. There is probably an underlying disorder that would need to be investigated. If all the nails are equally affected infections (Bacteria or fungus), immune system (immune-mediated) diseases, and metabolic diseases (Excessive levels of growth hormone) are possible. Congenital disorder as well is possible if the nails have always been like that since he was born.
A skin scraping may be taken to determine what type of a skin condition your cat is experiencing, and a bacterial or fungal culture may also be taken for further analysis.
