Thank you for waiting. Since the spot is not affecting his normal eating and behavior patterns in any way, this is not an emergency situation. There are several possibilities. It could be a tiny wound that has gotten infected. It could be a growth/tumor of some sort. There could be a parasite.
A tumor seems most likely. There won't be anything you can do about that on your own. Tumors can be benign or malignant. Malignant ones are less common. They can be any color. You can watch this orange spot over the weekend. If it continues to grow, I would schedule a vet visit early next week.If it stays the same, and still doesn't affect him in any way, you can take a wait and see approach. However, if he were mine, I'd schedule a vet appointment anyway. No matter what it is, it will be easier to deal with in the early stages. If you need a vet, this link will take you to a directory of them:
If you have more questions, just let me know. I hope this will be soemthing minor.
