HELP! I woke up this morning and came to say good morning to my piggie, Cinnamon. I noticed that she has a small raw spot on her front right paw that was not there when I put her to bed last night. She is chewing on it and "whimpers" the sore is about the size of a mechanical pencil erasers surface. I am new to owning her she is only 4 months old. She is a solo guinea pig and currently is in a store bought cage. She has free floor time every night for at least an hour. I take her on my enclosed patio. I don't know what to do. Please help!
