So two of our cats found themselves with mildly weepy eyes - nothing too unusual, especially for this time of year. Within a day, however, Momma's third eyelid was showing across a portion of the bottom of her eye.....and a day later was covering her ENTIRE eye.
We got her into the vet and tried some eyedrops, but took her back two days later when it had only gotten worse, and her face was further swollen on the one side. Apparently it wasn't an eye infection at all, but a bad tooth causing all the problems.
Around about the exact same time.....Gronk started having the very same symptoms in the very same eye! By the time we picked Momma up from having her tooth pulled, we were dropping him off to have some of HIS teeth pulled. Both had to spend two nights at the clinic and were not happy, but it had to be done.
Then there was the day Pennywise discovered the pillow of himself that Jane had made.....priceless.
