Thanks for using Petco Pet Education Center, formerly Petcoach! It is hard to know what this is as it could be many things. I think it is likely mucus and nothing to be concerned about. If he is otherwise doing fine, I would just continue to monitor him for now. If at any point he develops diarrhea, inappetence, vomiting or any other concerning symptoms of sickness, have him evaluated by a veterinarian. Good luck and have a great day!
