Since you mentioned it, I noticed in his mouth, on his gums, there are small dark spots that look like melanin deposits. I didn't notice them till I got him inside and when I posted the first photo of him thought it was from hjim getting in a fight.
I looked it up and orange cats have what it called feline freckles, or lentigo:
"Why Do Orange Cats Have Black Spots?
The most common reason for these dark spots is lentigo, a genetic condition in which there is an increase in the number of epidermal melanocytes. As these pigment-producing cells multiply, small black or brown spots appear on your cat’s face.
Orange cats are not the only color affected by lentigo. Black spots can also pop up on
tortoiseshell,
calico, yellow, and flame-point cats. Middle-aged to older cats are most commonly affected, but lentigo can appear in cats as young as a year old.
What Are the Signs of Lentigo in Cats?
When lentigo first appears in cats, it often pops up on the lips as
tiny dots, before spreading to the eyelids, gums, and nose. As the cat ages, the spots will become more widespread and may grow larger. Often, a small cluster of spots will grow together to form a large patch of pigment.
Small lesions may appear close together, discoloring a larger area. The lesions are either brown or black, small in size, and are usually flat, but may appear raised. With a clearly defined border, there is no redness or other skin changes surrounding the lesions. Cats also appear to be comfortable with these “freckles,” as they do not seem to be itchy or irritating.
What Are the Causes of Lentigo in Cats?
While freckles are associated with sun exposure in people, the exact cause of lentigo in cats is unknown. The appearance of these feline freckles does not seem to coincide with increased sun exposure.
Regardless of the underlying trigger, lentigo spots result from pigment-producing cells called melanocytes making more melanin than the surrounding skin. It is thought that the gene that codes for orange coat color is unstable and reverts back to its more natural "non-orange," dark gene over time, but this theory has not been confirmed.
How Is Lentigo in Cats Diagnosed and Treated?
Veterinarians often diagnose lentigo based on a thorough physical exam, the presenting clinical signs, and by checking for any other health conditions. Occasionally, lentigo spots can appear similar to melanoma, so your veterinarian may take a fine needle aspirate of a suspicious spot to search for cancerous cells under the microscope.
Lentigo is not a form of cancer, nor will it grow to become cancer. The only concern is that lentigo spots can mask melanoma spots, which makes routine veterinary exams critical for monitoring. If you notice a raised black spot on your cat, contact your veterinarian, as raised spots tend to be cancerous more often than flat spots.
Since lentigo is a benign, cosmetic condition, like human freckles or age spots, there is no need for treatment—simply enjoy your kitty’s freckles."

It worried me that it might be cancer at first but he doesn't act like it hurts or he is in pain. He had some soups treats tonight for Christmas. but I don't think I can get a shot of them unless I catch him yawning.
It's just the two of us and he likes to be near and sleep close to his Dad, the big Shotokan tiger. Dad will be taking his little boy to the vet after the 1st for his shots and will mention it.
