I would just observe the bite. If it gets infected (pus) or you have a red
line running up your arm, see a doctor.

Gail's advice is good.  Keep the wound clean.  If it gets infected, get to
your doctor as soon as its convenient.  If you start to see a dark line run
toward your heart from the wound, RUN to the ER.

We are assuming, of course, that your cat is properly immunized.  If not,
it's a whole 'nother ball game, and you should take both your cat and
yourself to your respective doctors.

Yes, keep an eye on it.  Cat bites can be very nasty, but yours doesn't
sound drastic.  It was alright to use hydrogen peroxide *once* to cleanse
the wound, but don't use it again.  Repeat applications can actually slow
down or prevent the healing process.  Also, is your tentanus immunization
up-to-date?  If not, call your doctor and see if you should get one.  And
don't delay.

One word for cat bites:  neosporin!  If a red line appears to be coming
out of the are of the cat bite, then get thee to a doctor.  The only time
I've heard of really serious problems with cat bites is when the person
bitten had diabetes, but I could be wrong -- always a possibility.

I've had my share of bites and deep gouges from cats over the years.  If you
keep it clean and put antibiotic ointment on it then 99% of the time it
heals ok.  Unless it starts getting extremely red and pussy you don't have
anything to worry about.

I beg to differ, I had a deep bite on my hand some years ago.  The area
around the bite turned red for almost an inch.  I went to the doc and
he said to watch it and if it got any worse, he would put me in the
hospital.  Peroxide etc isn't going to get into your blood and attack
the infection, that's silly.

Yeah, I heard about that.
No wait, that was Komodo Dragons.
Never mind.

Cats have pasteurella bacteria in their mouths that can make a nasty
infection sometimes. Don't worry about amputation, I know you'll catch
any problems long before then!

If it's more swelled and red tomorrow, I'd go into the doc. My sig.other
was bit by one of our cats long ago and it was a deep puncture -- hard
to clean out. After a couple of days his hand swelled up like a glove.
All it took to fix was a trip to the doc for some antibiotics and to
have it cleaned out again.

I got bit by a stray we were trying to wrestle into a carrier. Mine was
worse the next day like yours, but I kept running hot water over it and
putting OTC antibiotic cream on it, and it was better the following day.
That was as long as I was going to give it before going in.

You're smart to keep an eye on it, and I hope it's better tomorrow.

I have a testy cat that doesn't like being dragged out of the garage
when it's time to come in, and he's given me a few good chomps.

I always find that washing the cuts IMMEDIATELY with SOAP AND HOT
WATER, several times, does the trick. Wash and dry. Wash and dry. The
itching goes down in ten minutes, and I'm home free; just a matter of
time until I'm completely healed.

Your body will tell you if it's something requiring further action --
by swelling up, reddening, and itching or burning you.
