What causes skin ulcers on my cat's skin? There is literally no physical reason like stratches, bite, hit etc. What could cause it? They are red and open wounds, sometimes inflammations.

Your cat could have allergies, to fleas, substances in the environment, and most often, to foods. I recommend getting your cat seen by your vet for an exam and treatment and consider doing a food trial. There are commercial foods that have a single protein source. Try feeding your cat a food that contains a protein that he has never been exposed to, such as duck or venison. If his skin improves then he likely has an allergy to the protein in his old food.
