This is a warning for anybody getting a dental treatment for their cat: our Kili (British Shorthair, 13 years old) had to have 3 teeth removed last Thursday (2 Molars, 1 pre-Molar). The surgery went well and we were able to take him home around 5 pm (he was given a pain killer and a 48h lasting antibiotic). Around 9 pm I noticed that there was a little yellow discharge from one eye and that the lens of this eye looked a bit opaque. Since Kili has a slightly 'smooshed' face his eyes are occasionally teary, so I just cleaned it, put some eye drops in and thought nothing about it. The next day the eye started to swell up and it looked uncomfortable. Kili is usually very cuddly, but he preferred to sleep in a different room that day. He ate a little, but we could tell he wasn't happy. We decided to call the vet and got some antibiotics and eye drops (we didn't take Kili to the vet for this as he hates driving). That evening the eye looked awful, the lids were red raw and completely swollen shut and the poor cat was hiding under the sofa, so we took him back to the vet (emergency cover) around 9pm. He wouldn't let the vet examine his mouth and he was visibly uncomfortable and swollen. They kept him overnight, giving him fluids and antibiotics. The next morning the vet who had done the operation informed us that it was ocular cellulitis, a rare but very dangerous (possibly even fatal) side-effect of dental surgery. Kili was kept at the vets until Sunday afternoon, he had antibiotics 3 times a day and several different eye drops every hour. He is now home with Gabapentine twice daily and 4 different eye drops 2 to 3 times daily. The swelling of the lids has come down and he can open his eye, but it is still swollen and very red and opaque and we will have to see if he can even keep it (so far the best in the worst case scenario is vision loss rather than an eye enucleation).
So for all of you out there: if you have a cat (or any other animal) that suddenly has eye problems after a dental procedure: THIS IS AN EMERGENCY and needs veterinary intervention IMMEDIATELY! Please feel free to share for prevention.
