Thanks for query,
You have infection of wound.
Heavy antibiotics like augmentin
will work on it along with cleaning & dressing.
The risk of getting rabies
from a cat is fairly low, with most cases of rabies now occurring in wild animals.
The animal quarantined and observed for 10 days if possible, or if you really think the animal could have had rabies and they can't find the cat to see if it has rabies, get human rabies immune globulin
(HRIG) and beginning the first, in a series of five, rabies shots as soon as possible.
