I have a large, male Maine coon with a food allergy on a grain free diet that has always had dry skin. In the winter the cool air humidifier runs 24/7. A few weeks ago, I found a flea on him after a trip to the vet. They gave me Para Defense, a new generic med. Two weeks later and I can't find a flea on him but it had dried out his skin! The last five days he has been taking omega 3 vitamins with his wet food but will NOT STOP biting his paws!!! He's no longer ripping out fur, behavior, bathroom and eating habits are all normal, just the constant paw biting! Any suggestions on how to get him to stop? Anyone else experience flea meds drying out the cats skin?
