Sometimes skin issues are traceable to thyroid problems or kidney disease as well as allergies.

And depending on the flea and tick control you are using you might try stopping that a month and see if there is any improvement. Not all animals do well with all medical products.
If you are seeing problems on the cats and the dogs then I'd suspect something contagious or a product you use in the house that the animals are sensitive to might be the cause. If its just the one cat then he might just be sensitive to a food, an inhaled item, or again a cleaner or something else in the house. If you've not checked his thyroid function that might be worth doing.
If your regular vet is not helping then I'd suggest seeing a veterinary dermatologist.
Hope this helps you!
