My cat bit me (she was terrified at the vet's office) and I was fine. The bite was on the back of my hand and not very deep. The vet cautioned me that, especially since I was on immune-suppressants, I might want to go straight to the doctor and get antibiotics. I didn't because it didn't seem that bad. It never got infected. However, I also have a friend whose husband's finger got infected within 24 hours and they had to admit him to ER! (He is *not* on any immune suppressors!) Perhaps I was lucky... they are not to be fooled around with!
