This is my little dude Cheep. Really not sure what to do. Out of nowhere I found a gooey substance all over his head. Through some google searches I found out it was mucus. He keeps shaking his head and covering himself in it. I gave him a little bath and wiped him off. Is this bad? Should i take him to a vet? I’m super nervous and cheep means everything to me. Please let me know.
