Why is my cat losing hair and has black dots/scabs on his nipples?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 13 lbs

My male cat is pulling off all his hair on his nipple ,and he has little black dots on the belly area around the nipple. They feel like tiny scabs no bigger then a pen dot. Also has pretty bad scabs on the nipple not talking about the pen dot ones. I'm not sure of his age but we have had him for 6 years. His appetite is good and water intake is good. He eats sensitive stomach science diet. I want to know what could possibly be wrong with him and should I take him to the local vet.

These little black dots on Boo Boo could be flea dirt, which is flea poop. This, plus him pulling off his hair, are signs he has fleas. You don't have to take him to the vet yet, I can give you a flea treatment program for him. First, I would give him Capstar. It's a one time pill that starts killing fleas within 30 minutes. Then follow up with a spot on treatment, such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. If Boo Boo is up to date on his flea treatments, then I would have him seen by a vet to diagnose what is causing his symptoms, which can include allergies.
