It's not deep at all. It still is quite sore and red around it and my hand is swollen a bit but it isn't horrible. Why do I need to watch for illness in the rat?...like he could get something from me?? What do I watch for? My friend is the retired dog warden and she said they do not do a rabies quarantine in for rats. So I don't have to worry about that. He is in quarantine anyhow but still...no visit needed from the health department.
Just in case he got something from ingesting your blood, or if he becomes sick, that means you may have gotten something from him too, so if he gets sick you should see your doctor as well.
The chances are very slim that anything serious will happen, it's just a good precaution to take.
Just keep your hand clean, and i'm sure you will be fine!
