Hello, I came onto this website to find out if my guinea pig is okay. I was getting romaine lettuce for my piggy with him in my grasp, but I lost my balance and he ended up being dropped onto the kitchen floor. It was about a 3 ft drop. I immediately picked him up and he wasn't in shock or anything. So I put him onto his pillow and examined him thoroughly to check for any broken teeth, broken nails, any difference in walking, etc. He is eating well and walking perfectly fine but he has a wound on the left side of his lip/mouth. Should I be more worried than I already am? How long will this wound take for him to heal?
