Just got back from the doctor. I have been feeling strange all day and two of the wounds were leaking fluid. He confirmed my fears - there is infection under the stitches. So he pressed and emptied the pus and then injected the sites with antiseptic. I have to go back in two days. Very nice local doctor though, he and his wife have four cats, and he could hardly believe that I had cat bites. All a bit scary, specially since I have been taking my antibiotics religiously since last Thursday.
