I have a box of 70% isopropyl alcohol wipes in my desk at work and haven’t yet found anything they won’t clean off a user’s screen (short of actual damage like scratches or cracks). Better to not use anything stronger just to be safe.
Our siamese has the same. It’s a sort of feline herpes that manifests itself in chronic sinus issues and she creates some of the largest snot-rockets I’ve encountered…human or otherwise. They end up everywhere and if you don’t get to them soon enough, they harden into something resembling epoxy resin.
Right there with you. One of ours has crazy sneezing fits, she’ll rapid-fire off a dozen or more violent sneezes in a row. Thankfully hers are pretty dry. Occasionally the virus will flare a little more and she’ll get gunky eyes too.
I tried to return one of our defective cats to the manufacturer but my wife made it pretty clear that the household power structure had me a couple of notches below said defective cat and that if anyone was getting returned, it was going to be me.
