My cats both had severe untreated syphilis when they were kittens which fucked up their sinuses. One of them just has a leaky eye but the other has two fucked up inner eyelids, two leaky eyes, and a VERY leaky nose. She will have sneezing fits randomly and it’s like D-Day. We take cover or quickly scoot her to the hardwood floor to limit what she covers in snot lmao. Love them both to death though
