Cat hair loss on legs and back: Is it over-grooming or something else?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed | 6 lbs

a mother cat and her kitten now about two years old are both losing hair on the backs of their legs and the younger one on her back, could they be over grooming each other ... as they never separate I have other cats that are not suffering from this they are all indoor cats well fed and kept clean, I just realized could it be grooming ??? they do not chew, I do not find them scratching, they are near the other cats I am puzzled but in writing I think they are over grooming is that possible? TY

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear that Zorra and Ellie are having problems. Over grooming is possible but other things may be going on such as a fungal infection (ringworm), bacterial infection, external parasites (flea, ticks, mites), etc. It is best if you have them examined by your veterinarian so a cause can be determined especially since some of the things mentioned are contagious between cats and people living in the house or who have contact with the cat/kitten directly or indirectly through the shed hairs in the case of ringworm. Your vet can look at these areas and advise a Woods lamp exam, fungal culture, or other tests to determine the cause. They can also advise treatment if any is needed. Good luck with them.
