Why is my cat suddenly biting her nails and what should I do?
Hello. This could be a behavioral issue, or a behavioral issue plus paronychia ( skin infection around the nail/claws ). Even though you do not see anything unusual, a veterinarian can examine the skin, do a skin impression to see if there is a population of bacteria or yeast organisms present around the nail beds. An appropriate treatment can then be started. Often, this could also be an indication, & the only evidence of, an allergy. Allergies can come from the food or the environment & can be challenging to distinguish in cats with mild symptoms. So it is very helpful to get professional help with this. Good luck & thanks for using Petco Pet Education Center, formerly Petcoach.
