Wandering cat named Marlin

Dear neighbors, If you are the owners of a gray-ish stripped cat named Marlin My husband posted before and we didn’t see Marlin for a week or so but he has been back. He fights with our cat in our yard and even got into our house and came up to the second floor. Please if this is your cat keep him inside. I don’t want to call the Animal rescue but next time he comes in our yard I will have too. Thank you
