Please, keep a watchful eye on the bite!
I got an innocent bite from Artie while feeding him after his dental.
He was still 'high" from the pain killer (tooth pulled). He was rubbing and going in and out of my ankles and suddenly just bit my ankle.
I ignored it and 2 weeks later I had a really bad, strong infection, under the surface of the skin, which could and would spread very fast if untreated and I would have gotten extremely sick-throughout my body.
Had to go to the Emergency room be because 5 inches around it was red, swollen and itchy.
They had to give me and IV, take a culture, started me on one antibiotic. When the culture came back they called and changed it to another one which was better suited to the infection.
They told me how bad cat bites are, and they even had to report it to the state.
I would be very concerned about your thumb. It is a sensitive, tough area to heal~ and it will be sore for a long time...
I would go to the doctor to check it out..Urgently, not waiting for the next available appointment....
