The cat, the board, or both? lol

I have a bunch of cats in the house, they use the kitty litter just fine.
But I did find a hairball on a machine once, that's bad enough. Oh and
Chinese manufactured KVM cables must taste like catnip to young cats (glad
they grew out of that).

Cat urine seems to be very concentrated ammonia, but the copper traces on a
circuit board would be green and show damage unless the board coating did
not get penetrated. In other words the damage should be clear to see if it
was damaged.
