Is possible it may clear up on its own, but I wouldn't risk it.  Eye
infections left untreated can cause permanent damage.  Treated properly
they will clear up and there will be no lasting damage.  It's good that
your taking her tomorrow.

put the antibiotic in both eyes.  Follow the directions; squeeze some in
and smush it around (lightly) with the closed eye(s).

and even when it clears up, keep using the ointment for another week or so.

My New kitten Candy (8 weeks) has got conjunctivitus and has to be
given one drop in each eye twice a day for 7 days. The ointment is
"Fucithalmic Vet" and she has been having it for 4 days now and her
eyes do look as though they are getting better. Her eyes don't sound as
bad as your cats are, right enough but I woould say make sure you treat
both eyes for the infection at the same time and I'm sure they will be
fine as the cream is most likely an antibiotic.

sometime it can take weeks to clear up.  Use the ointment they are giving
you.  IF it looks worse, or she stops eating drinking or being an obnoxious
kitten, then worry.

one of my fosters turned residents had a MAJOR swollen eye.  Just came on
one day.  She had been sneezing.  Took forever to clear up, but now she
looks totally normal.

adopted

What kind of ointment did they give you? My cat picked up conjunctivitis and
my vet started her on TAO (triple antibiotic ointment), which one of the
CVTs referred to as saline tears with a kick. Well, the TAO did nothing.
Most shelters have to treat upper respiratory infections very aggressively -
lots of vets don't use the same medications as we do at our shelter. For
conjunctivitis to the degree you're describing, we would use terramycin in
both eyes twice a day for two weeks - continuing to the full two weeks even
if it looks to be clearing up. This keeps it from coming back right away. On
top of that, we would probably also use doxycycline in 50mg capsules once a
day for the same two weeks. Check with the shelter where you got her and see
what they use - if it works on other cats in the shelter, it should work on
yours... it's the same strain running through her, after all.

Conjunctivitis left untreated can cause permanent damage. Sometimes it's as
simple as chronically watery/goopy eyes - you can try treating her with
500mgs of lysine twice a day. The tabs are pretty cheap, can be found at any
grocery store - you just have to crush them and mix 'em in canned food to
make it appealing to your cat.

URI in regards to sneezing can also cause an interesting side effect usually
only seen in shelters - what we refer to as "snot-rockets." Cats who have
URI symptoms chronically but are no longer contagious to other cats. It's
just really gross to have a cat snotting boogers all over your home for the
rest of its life.
